Maybe, though it says that Yamoshi became a Super Saiyan, and was then defeated, and then his spirit went in search of 6 righteous saiyans to bring about the Super Saiyan God. The guy in those images may be the first Super Saiyan God who came about from Yamoshi's spirit, rather than Yamoshi himself.
The bit about the namekians learning about Yamoshi and recording the legend is pretty neat too. I wonder if Yamoshi's spirit or Yamoshi himself will play a role in future story-arcs.
