I think I see what your attempting to do. You have the on table commands have their baggage held in army baggage but with two fewer as the other baggage is held as command baggage with the flank marching command (you could also do this for a command in ambush I suppose?). It might be a cunning way of making your opponent believe all your commands are visible and on table, you might find though that if your opponent tots up the number of elements in the on-table commands he would soon realise there are not enough ME on the table.
Actually, I think you have it back to front.
I deploy my three command army on table, including some troops deployed in very deep formations. I place four real baggage elements plus four fake ones behind them. I roll four PIP dice as required by the rules.
My opponent looks at my army and thinks, "Eight baggage elements...he must have four commands. There are some troops deployed very deep there, so they must be produced by exaggerated numbers. That gives him spare points to afford a command I can't see. Is he flank marching, delaying or ambushing with that command?"
In reality there is no fourth command, but it might distract an opponent enough to detach troops to cover a non-existent flank march.
