There's no other reason possible except a mistake. With an ask at .0915, it probably would have taken only a few minutes to sell that 100K without dropping the price. The .092 earlier today was snapped up very quickly, and that itself was an unnecessarily low ask.
That's what the optimists of the class say. Pessimists say they've seen this action before and sometimes it means the price is going to drift down to that level.
