He worded it strangely... I think he means how FFTA's system switches by individual units rather than each entire army making all their moves in one go, like FE. Speed determines attack order, that sort of thing. So more like taking turns in chess.
Oh you mean like FF10's turn order queue. I wouldn't say I prefer one or the other, both give a different dimension to the flow of battle, and completely changes how one might approach an enemy force.
