I can confirm this happens in every version of bash, at least back to bash-2.05b which is as far as I can go, but only when history expansion is enabled (set -H or set -o histexpand). I think this is intended behavior, although I'm someone who routinely disables histexpand, so I'm not as familiar with all of its features as others might be.
