Looks like this change was made deliberately:

  revno: 102844
  committer: Kim F. Storm <storm@cua.dk>
  branch nick: trunk
  timestamp: Fri 2011-01-14 16:06:17 +0100
  message:
  * emulation/cua-base.el (cua--init-keymaps):
  Remap exchange-point-and-mark in cua-global-keymap.

The docstring of `cua-exchange-point-and-mark' says it does not activate
the mark.

Kim, could you confirm that this was the intention?
