The last time I remember to observe many smallish orders of the same kind was during a larger dump and they were on the selling side.
But how does micro-orders on the bid manipulate the price up?
Consider. If they get hit - what color will all the prints be...
But they are placed there for someone desperate to push the price the other way

And if they arent hit.... then, it continues on without them.
Really though, thats all nonsense. If they are hit, then they might make a few stupid people follow them. Otherwise nothing happens.
