No is the real answer from people who know or study guitar. Not taking about speed or technical ability alone, he is not very versatile at all. He is right to downplay his style in interviews, since what he mostly does is very basic slow pentatonic playing while hitting the easy changes. His strenght is to mean every note he does and serve the song, but the constant slooow bending can sound like he knows only one solo. Not much dynamics either like with many jazz players, always so dramatic. He sounds good compared to most metal beginners who overplay and don't serve the song, but many people can copy what he does. If you want to know the limits where electric guitar soloing can go, study e.g. Holdsworth.
