That’s rpm, suse Linux 1.0 was never built off the same source or installer that Redhat Linux was.

Do you have a historical example where any suse distribution used redhat based source? As opensuse as I said only used the rpm package manager, it never used any other components of a redhat derived install.

Source: I work there and can find zero redhat strings in any old source code from that era, the old greybeards took offense to the implication that suse was ever based on redhat other than using rpm which at the time was about it for packaging.

All they did was start to use rpm instead of tar for packaging.

Opensuse and fedora have no common history though? Just because it uses rpm doesn’t make it a red hat derivative.
