You're not being dense -- the way we're using it is indeed a bit odd.
But it was a concious decision to leave it like this: the reason is that
we've been using these two digits to indicate patch level rather than
major for so long, that is seems less likely to break version parsing
tools if we continue to do that. So the patch level for release 10 is
going to use the last two digits only, with the two middle digits
remaining constant 00 forever.
