Bernie's right about what the single rotation will do - which does NOT
seem to be what the intention of the double rotation would be.
I ran into this very problem trying to compensate for a bug in the
texture mapping in WebFX; I found that I had to do 2 separate rotations
of 90 degrees to get the object oriented the way I wanted.
