Ryze's E is never a single-target spell, and full spell vamp is only applied to one target at a time, so that doesn't really change things. It's still true that the spell vamp on his ultimate is inflated, since most of your healing is diluted. Again, this is mainly due to Ryze's kit being super-archaic.
