What caused this spin?

Question in the title really?

I've heard Imprezas can suffer from lift off oversteer, but it all seemed so calm then, bam, gone! Can some explain? And no it's not me!

It looks like he went into the first left too fast, then lifted too much started to spin left. overcorrected plus missed his braking point for the right turn and let it spin out to avoid the wall. Pretty lucky to get away without doing any damage http://s23.photobucket.com/albums/b372/xanderjones...

A variation on the classic 4wd overcorrection - wind on too much opposite lock, leave it there too long and then lift off = car fires off whichever way the front wheels are pointing.
Quite common for drivers used to RWD to apply too much lock when catching slides in a 4wd car, and you do have to take the lock off again very quickly to catch it smoothly.
ETA: Most likely in this case the lift was to turn the car into right-hander rather than the common panic-lift, its quite possible that if the driver had let go of the wheel as he lifted it would have corrected itself. The line between looking like a hero and spinning is sometimes a fine one.

I agree with whats been said so far, lift off oversteer on the left and then snap oversteer to the right cos he was still on a trailing throttle combined with the weight shift when he steered right, if he'd nailed the gas as he turned right it would have probably bitten and gone round, either that or because it's a P1? he might have had the driver controlled diff screwed right to the back effectively making it rear wheel drive?
def no DCCD in the P1. I found mine had an interesting characteristic with regard to speed at turn in. If you got it too fast, the back would break away very early indeed and opposite lock could catch it but you ended up going pretty much straight on. Too much opp lock and you had a tank slapper! Well set up RWD cars seem more tolerant to entry speeds too high.
I looks like the P1 in the Vid goes in too fast and breaks early and the rest is history.

not much you can say to that ... spot on I think that that car could have got round that corner at that speed.
If you watch the drivers hands you can see he has the classic "Leant back, one handed" Steering style, and as he turns in he uses his right hand only, with a locked elbow, to push over the top of the steering wheel. Then as the slide develops, he jerks his hand back to the right, and no doubt his arm is well loaded too due to the locked elbow, so the lock springs off to the right leading to the tankslapper.
I think that poor steering technique was the primary cause of the skid, and poor correction of the developing slide worsens the situation.

Give the guy a break! He's on a closed track, taking part in a speed competition. He overcooks it, spins, hits nothing and does no damage. It's called "having fun responsibly"! Plus, he probably learned better car control from the experience without puttng anyone else at risk.
Oh yes, and Imprezas can certainly be subject to lift off oversteer and, when talent is lacking, to ongoing tankslappers! I know this 'cos I found out on a damp Beford Autodrome. Like the guy in the clip, I was having fun, I learned something useful and I was at no risk of hitting anyone or anything significant (and I didn't spin, which impressed my instructor!).

Not wishing to be unkind, it's a pity there isn't an 'unadvanced driving' forum for these types of incidents.
Dunno, looks pretty advanced to me.Here`s a guy pushing his limits in a safe environment and generating a healthy debate into what went wrong. A typical group learning scenario if I ever saw one.
Would be interested in why you think this qualifies as sub standard driving.
