Without going into what a cross trade is,,, I'll re phrase what I am thinking,,,,here's a scenario

If broker x knows something (buy the rumour, etc) they can "push" (advise)the buy ABC to client base Y and "push" the sell ABC to client base Z.

Thus we see the broker "favouring his client base Y,,, ie this could be the clients that generate him/her the most income and client base Z could be the "bunnies or cannon fodder" to achieve the churn of shares that the broker needs.
