Confusing text in git-prune.txt

From git-prune.txt:

    [...] prunes all unpacked objects unreachable from any of
    these head objects from the object database. In addition,
    it prunes the unpacked objects that are also found in packs by
    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
    running git-prune-packed.

How can "unpacked objects" be "found in packs"? Maybe the first "unpacked" should be "unreachable". But if that's the case, wouldn't this be better:

    [...] prunes from the object database all objects unreachable from
    any of these heads. Prunning already-packed objects is done with
    the help of git-prune-packed.

Thoughts? Or am I reading the original text wrong?
