I don't think so , I mean the dude has perfect Senju/Uchiha DNA ratio ( half his body is Uchiha and the other half is Senju ) and on top of that he has the GM sealed in him which is full of life force as stated by Yin Kurama ?
Different conclusions are reached when one fact is viewed from two separate points of view. When that happens, there is no immediate way to judge which point of view is the correct one. There is no way to conclude one’s own conclusion is the correct one.

Nagato died using the same technique, while being synced to the Mazo. There is this as well as the tremendous strain that was put on his body by the simultaneous release of the bijuu.
