Yeah the shot right before that is his A-wing spinning out of control along the SSD hull with laser fire all over the place and an x-wing right behind him that gets blown to smithereens. I think it’s pretty well implied his A-wing has been shot down and (at most) he’s just doing his best to make it count for something. I think an argument could also easily be made that he was totally out of control at that point and it was just blind luck (or the force…) that he happens to crash directly into the bridge. But whether he has any steering control or not, if you watch the scene I think it’s pretty obvious he’s crashing because he’s been shot down, not because he made a conscious choice to be a kamikaze.
