New MK4S kit with MMU3 kit assembly - Really modify nextruder?

I am currently building a MK4S (could be MK4, no difference in regards to my question) and MMU3. Most of it is done besides Nextruder and MMU3 modifications for Nextruder.
In the assembly instructions I am supposed to build the MK4S Nextruder and then disassamble it again to make the MMU3 modifications. Seems pretty pointless to me and especially a complete waste of time.

Now, considerung I'm certainly not the only of Prusa's customers who purchased the MK4(S) kit together with the MMU3 kit does anyone know why I should assemble the Nextruder to just disassemble it again and build it with MMU3 modifications?
Is that required to be able to finish initial calibration of the MK4S? Or is it just the fact that Prusa didn't bother to create a separate set of instructions for all who build MK4(s) together with MMU3 initially?

I can hardly believe that if Prusa is selling fully assembled MK4S+MMU3 that in the factory they build the Nextruder and then disassemble and modify it afterwards.
So the question is, if I'm combining both instruction sets (MK4S and MMU3) and build the Nextruder including the MMU3 modifications - will that cause any issues during initial calibration?
Or do I really have to finish the MK4S without MMU3, run the initial calibration and then modify the Nextruder?

So, after being brave and finishing assembling MK4S and MMU3 without building MK4S and then disassembling parts again to modify for MMU:
It works to directly include the MMU3 modifications when building MK4S. Calibration and everything else afterwards works just fine.

So no need to waste time during assembly by following both (MK4S and MMU3) assembly instructions separate.

Only thing slightliy tricky is reading two manuals at the same time and always picking from the right one.
In case Prusa is reading here: Please make a separate chapter in the MK4S manual: Building Nextruder with MMU3.
