Aside from what the person said above, It's probably because the blood wasn't fully assimilated yet. It took awhile for Vanilla Ice to full transform, and a much longer time for Dio to actually achieve complete control of Jonathan's Body, so even if he did receive Joseph's Blood, it may have not been completely converted yet.
