This assumes that the opponent knows better which positions need what amount of time. It becomes interesting if both sides make this assumption, then we have a feedback loop.

This is not done on a per-positition basis, but based on average time use. Nevertheless, it is suspect if the oppoent suddenly thinks very much longer than average. He must have see a complication at large depth that invalidated what you ca see at lower depth. So should you really stick to a lower depth in that case?

As to the feedback loop: this is the reason for a factor < 1, like the 0.9 in the example. You do't wat to fully copy the opponent, if he is using sub-optimal time. You want to profit from his 'mistake' by gaining a little time on him, which might build up to a decisive advantage later in the game, if he does it too often. But being too greedy in that respect might mean you acquire that decisive time advantage only after you are checkmated, so you must re-invest part of it to isure against that.

Next question, this time allocation scheme doesn't sound too complicated - does Kingslayer use it?

No, it doesn't. But KingSlayer is an extremely simple engine, just one step up from micro-Max.
