Yes, this doesn't look like an attempt at a flash crash, the way that walls are position (cautiously high and holding well), sustaining the price to make it look like a consolidation but then break in a tick. It surely shows no volume, but what it also doesn't show is ; how fast they vanish and at what precise timing they do.
I'm afraid, their is no real intent to dump behind those well organized move. Attrition of the cash flow of the bull in a slow down trend seems more likely to me. Tiny move down after tiny move down, pushing them closer and closer of the consideration of the stop loss option.

Well If I were in that position and had interest in creating more than a flash crash but to accumulate coins over a longer period of time, I'd try to create delusion more than fear.

It doesn't mean it will work, but I think that's what is being try to be achieved.

I think it's because they didn't retrace as much as Gox/stamp during the up-move, so since PA were closer to the support level it was easier to start from there. but still, I agree, it's strange. Mostly since Gox has a "spread away" bid wall. Anyway, we getting closer to $841 there, then it should  catch-up with China.
