I'll point it out, since it might be important that the colour of the hair and eyes differed from the childhood friend that Satou knew, and it was mentioned that simple reincarnation is not enough to satisfy the needs.
Suzuki would've used things from real life as inspiration for his games, so when "recalling" Satou's memories, Suzuki would've conflated it with bits of his own life.
That is quite unlikely to happen, as Suzuki Ichirou was a rather 'do as told' programmer. Although I can't deny the possibility, as we don't know anything about the games he created while not working, but likely that they would follow a certain pattern, dictated by other games, as is the norm.
Can't really say much until we get a more fleshed out flashback, but that's unlikely to happen any time soon. I'm more inclined to say that a few different realities meshed together and Satou got the feedback there. Possibly? Unlikely. Ah the mystery, it's killin' me.
