His v1 vocal and v3 have the same tone. The range of v3 is bigger, but v1's engine had more "give". This allowed him flexibility. The v1 emgine added a lot of distortion, in addition.

Voices also change slowly over time. Smokers may make their voice go coarse. Professionals singers may get better at singer... I do not expect every vocalist to never stay the same. In addition, it gives some reason to go back to old vocals.
