One could imply that, and one could also be wrong. Tape is not an option for white conductors, it is a listed option for green.
Go figure, I can't explain it, and neither can you.
The only thing that I can explain about that different is that it would be MORE critical for white grounded conductors which ARE INTENDED to have current on them and no voltage, versus grounding conductors which ARE NOT INTENDED to have either on them.
My guess is THAT makes ALL THE DIFFERENCE.
