Would an assymetric thrust reverser on engines so close to the normal thrust line, cause such a swing ? Dunno, but it isn't like being an outboard engine on a 747.
Look at a Learjet. Engines look very close to centerline, right? When I flew and instructed on the early Learjets including the 23, the advice was to go all the way to the stops with the rudder and just possibly you could reduce the input slightly. Anything less than FULL rudder was an invitation to more problems.
They may look like they are close but you will use a full leg of rudder on the -80 with an engine failure. As for the 747, look at the size of the vertical fin and the rudder.
