My understanding with the multi thing and the twin star is that whilst it is most certainly twin engined it poses problems for testing and issuing multi ratings.
The fadec for the engines mean that unlike the current batch of twins used for training there are no prop or mixture levers, just the 2 for go faster, go slower. Hence then going to an older less advanced airframe is harder than going from an old airframe into the twin star.
Sounds remarkably similar to a jet to me but ho hum.
