A few more older fans may remember the Robo-Robotnik issue from way back (not me, I'm too young, I just read it up on Sonic News Network).
The controvoursey (how the hell do you spell that?) about Robo-Robotik was that there were two of them, but Archie settled this saying theres one.
Why am I bringing this up you ask?
Because Ian Flynn is pulling this old plothole out of the grave!

Some argue that the version of Robo-Robotnik seen in StH #22 is not the same Robo-Robotnik in StH #19, as the two seem to have different histories. However, because Robo-Robotnik himself explained they were the same in StH #75, it is considered canon by this site's policy, despite writer Ian Flynn stating he believes there to be two Robo-Robotniks. This may change if the subject is ever revisited.
In other words, Ian is pulling out his "Screw continuity, I'm the writer" crap again.
