Nice tune, Pete!
I d/l'd it so I can listen to it later with headphones, so this may be incorrect, but it seems to me that when you start the keys/guitar trade-offs, they seem to come from the same point in the stereo field, more or less dead center. When I think of doing step-outs, the musicians might be side-by-side, but there's still a bit of separation, if only visually.
It just felt a little odd to me when one instrument "replaced" the other in space.
Of course, "odd" is why I love Ozric Tentacles!
