Good point, though the way I see it, he has free reign to do whatever he pleases at this point. Simply knowing the exact location of every Gate there is puts him at a tremendous advantage. As far as I know, he isn't certain what dangers he'll face in this Gate or the next, but he knows what trouble the Order would present on top of those dangers. Why not just say "screw it, the next Gate will be easier to grab", and leave the Order in the lurch? They can't be in two places at once.
Ehm, I'm not sure how much he really knows (or cares) about the Order. Last time he just snuffed their leader without breaking a sweat and probably forgot about that already. So, no - I think that if he recognizes them as an opposition, he won't think about changing plans. He will start Meteor Showering them.
