I have done force upgrades several times recently and I seem to recall that the active port is force uninstalled before its replacement is built. I was on a live server and remembered thinking how unfortunate this is.

Here is a quick test with bash-completion showing uninstall happening first:

$ sudo port clean --all bash-completion
--->  Cleaning bash-completion
$ port installed bash-completion
The following ports are currently installed:
  bash-completion @1.3_4
  bash-completion @1.3_5 (active)
$ sudo port -s upgrade --force bash-completion
--->  Cleaning bash-completion
--->  Unable to uninstall bash-completion @1.3_5, the following ports depend on it:
--->  	git-core @1.7.9.2_0+bash_completion+doc+pcre+python27
--->  	git-core @1.7.9.4_0+bash_completion+credential_osxkeychain+doc+pcre+python27
--->  	git-core @1.7.9.5_0+bash_completion+credential_osxkeychain+doc+pcre+python27
--->  	mercurial @2.1_0+bash_completion
--->  	mercurial @2.1.2_0+bash_completion
--->  	subversion @1.7.3_1+bash_completion
--->  	subversion @1.7.4_0+bash_completion
Warning: Uninstall forced.  Proceeding despite dependencies.

To use bash_completion, add the following lines at the end of your .bash_profile:
  if [ -f /opt/local/etc/bash_completion ]; then
      . /opt/local/etc/bash_completion
  fi
