I suppose it's possible, but if it were, I think the jet would remain on a constant heading straight past the steerpoint with that same 7-8 degrees of offset but it doesn't. As I wrote, it slowly (at first) starts to correct with the bank angle increasing as you approach the active steerpoint.
Actually, I first noticed it on the Nevada map where it did exactly the same thing. Heading Command is also off by a few degrees relative to where you set the heading bug.
