That's because C-c C-s is bound to pop-global-mark, which uses the
global mark ring, while C-SPC is bound to set-mark-command, which uses
the local mark ring. It is somewhat confusing, but it's standard Emacs
usage, not an ada-mode feature.

I don't know what ada-mode 4.0 did in this area, but I think earlier
versions of Emacs did not have the local and global mark rings.
