I suspect it was just cobbling things together to make it work. The Regina body looks for all the world like it was designed to be a 4-speed block, with the fifth cog added later. And then a sixth cog cobbled on after that. And a seventh, apparently, for those uncouth enough to venture outside the on-topic era.
It's one of the things that put me off Regina freewheels. How do you stock all those different sizes, threadings, etc? And what a pain in the butt to disassemble. No wonder we just sold a new freewheel to customers who wanted a larger large cog.
And then there's the designed-to-fail shallow two-slot remover, but at least they had the sense to change to a splined remover eventually (after Shimano dropped their Regina-compatible design and went to a splined design for their Dura-Ace freewheels).
Zeus had the right idea: all cogs splined the same way with the final cog threaded to hold it all together. Both slots and splines so you could use an old Regina two-prong remover if you had to, but splines for their thin-wall, Atom-compatible don't-have-to-take-apart-the-axle splined remover as well.
