Yes, take the account from the perspective of actual Apple employee, much more the one responsible for the side-project, and add your internet commenter "bogus" on it.

Being based on NeXTStep made it easy. People working ACTIVELY on it made it possible.

You seem to have forgotten that on top of NeXTStep tons of stuff had been added in PPC land that weren't at all present: Aqua, for starters, tons of functionality ported from OS 9, the OS 9 filesystem and much more. That NeXT had a x86 port several years BEFORE OS 10 (0.1) was introduced means absolutely nothing.

And by the time it did come out publicly, it also had a translation layer, Rosetta, to run PPC apps.
