Don't know - so won't say.
Your explanation does seem plausible. All against the little guy as usual.
Quite often you cannot buy or sell as many as the Market Size, so it seems to be a principle which is not strictly followed. Less than helpful - sorry.
Look closely at the trades, after a while you can pick out buys and sells and follow the patterns - probably best to try on a less busy day
