Because Spirit Visage would give back more reliable HP than spellvamp:

Ability Cost 4% of HP to cast, the abosrbed blob gives back 4.8% HP (4% x1.2)  - This works better than spell vamp (which is reduced by AOE penalty and enemy MR). Spirit visage also gives better stats, with more resistances and 20% cdr = 20% more ability casts.
