Yes. Since the non-zero rounds to one, the position should change to "relative' within one "frame" or millisecond or whatever after transition begins, thus allowing the 'transition-animation' (the part after the slash) to move.

At least, that's the theory. I could have done the same thing a transition between opacity:1 and opacity:0.999, or something else which would not be noticeable by a human. But that seemed more likely to illicit charges of being too-hackish, which I will probably now receive anyway.
