Yeah, pretty much.

R means release.
11 or 12 is the major release number
A B C is the minor 'number'

Sometimes the 'patchlevel' is added as a suffix, i.e. -0 then -1 then -2.

By tradition, the A release is so dangerous that only a select few
developers with full safety gear are allowed to test it in a special
closed facility south of Stockholm. The B release is the first one
everyone gets to see. Sometimes, the B release is followed by a C
release, for instance R9C was around for quite some time (you can
still find it on the downloads page).
