That may be an aspect of it, but...
I think that his use of Logic in particular is very relevant in this discussion, because not only it has excellent support for different temperaments, it also has Hermut tuning, which dynamically alters temperament of all the instruments played based on actual chords to reach perfect intervals regardless of the key you're in.

For those unaccustomed to hearing pure intervals it can sound like a high-gloss "sheen" that gives an unreal quality to the music. In a way it becomes "too perfect" and unnatural to those who are used to hearing the equal temperament that most western music is recorded in. I hear it a lot in some acapella vocal groups and I often find the sound off-putting and it somehow feels a little corny to me.
