I can't find anywhere on sourceforge or www.tcl.tk that explains these branches. Did I miss something or is this something that the developers just keep in their heads?

You could call this a quirk of general Tcl development.  When 8.5 was started, Carbon was all that anybody used.  As Cocoa extended its reach and 8.5 got long in the tooth, it was necessary to make it supported, but core development tries (sometimes too hard) for compatibility on release tracks.  Thus 8.5 main branch stuck with Carbon, and 8.6 (as it is still beta) was made Cocoa by default.

As there are are only a handful of core folks that focus on the C side of OS X, the knowledge did just rest in our heads.  Of course, you found the right venue in which to glean that info.
