These are not two different clipboards, they are different ways to
access the same one.

On UNIX and UNIX-based systems, in a terminal, ^C means to issue a
SIGINT to the running process, and ^V is a special character prefix
(as in, the next special character you type will be treated as
non-special).  These are kind of carved into stone, going back to the
early days of UNIX (more than a decade before MS's GUI with its ^C-^V
behavior) and since, so in order to allow access to the clipboard at
all in a terminal, you have to shift the characters.

If you select something in a non-terminal window and copy it (usually
with ^C), you can then paste it into a terminal with <shift>^V, and
the same is true in reverse.

AFAIK, there is only one clipboard.

The issue with what happens in vim when you use the + register sounds
like an incomplete or improper implementation in vim, possibly a bug,
and should probably be reported to the appropriate person (Bram
Moolenaar et al).
