Heh... it can't devolve into that because that's not true. ;)
I think we all agree on what a pure carve is (god, I hope), but I think the problem is different definitions of steering.
I agree with RideGuy's diagram, assuming the downhill direction is down my computer screen. If your board has that kind of "steering angle" during a turn, at that moment you are not purely carving. So by this definition of steering, the answer to the <b>OP</b> is no.
Sometimes its necessary to do that, like if you have too much speed or not enough trail width.
