Your mistake was assuming it was to do with the distfiles used to
build installed packages, but the above comment is wrong

-D deletes any distfile that doesn't have a hash value recorded
anywhere in your complete ports tree. i.e. it only deletes files that
have no use.

-DD   deletes any distfile that doesn't have a hash value recorded for
the installed ports i.e. it additionally deletes distfiles that
correspond to deleted packages, even though such files are still
potentially useful if you need to reinstall.
