I assume your working copy also happened to have local modifications
to it. Therefore, Subversion did not delete the directory.

Correct: Subversion will not add an item if one of the same name is
already there.

If subdir1 contained local modifications, rescue them, then delete
the directory. Then you can "svn up" back to the HEAD revision.
