That's false as well.  (transient-mark-mode -1) followed by C-SPC C-SPC
will create an active region.
Nowadays transient-mark-mode basically only toggles the behavior between
C-SPC and C-SPC SPC as well as between C-x C-x and C-u C-x C-x.

Yes, mark-active is weird and messy and so is transient-mark-mode.
The implementation is ugly, messy, and twisted.  Patches to clean up the
mess are welcome, but I see no bug here.
