Not necessarily, if you’re doing a multiple motor gearbox you could just combine in the gearbox, go straight to the shifter, then adjust in the chain. Doing it this way could actually be really helpful as only the smallest sprockets come in nice sized bores and you need a very large sprocket if you only want to drive the wheel(instead of the whole shaft) in your chain.

National champion team 469 used the exact same(or at least very similar) shifting design in 2003 with two motors per side without any trouble, even though the shifter was very late in the transmission.
