It probably is. I can't remember any reason for Naruto to summon anything during his transition from reliance on:

Evil Fox Chakra -> Elemental Chakra -> Natural Chakra -> Good Fox Chakra.

I've barely watched the fillers and don't remember Gamakichi at all. I did notice that he was no longer smoking a pipe in the episode prior, but I didn't make the connection. His brother must be fat as fuck.
