it seems to be working as expected. destination is warped towards source at beginning and then as you keyframe the warp (the morph) it blends from the Source into the destination. Still sucks that it only has one global warp control though. It would be nice it it was like all the other morphers from elastic reality to shake to re:flex that all have warp and mix controls per spline group. :-( This one as with it predecessor to have fine control of the morph requires multiple morphers. :-(
