Don't know about the 104 but I remember being taught that fast jet some types of that era (possibly including one I flew, memory fails me on the specifics) had a limitation on the number of consecutive rolls, ( a possible limitation F-16GUY has mentioned) to stop the effect of inertia coupling building up and becoming err, to say the least, nasty. So for example one might be allowed no more than one continuous 360 roll at a time only.. .Since the BAF pilot was stopping rolling to do his "bumps" he'd be complying with that type of limitation.
