No, first parameter to "snapshot" command is a path to filesystem you want
to snapshot, but second parameter is just a label you want to assign it.
See hammer2(8) for details.
So you create a snapshot for example like this:
hammer2 snapshot /home/mydir mydir_test_snapshot

Find a snapshot of your interest with "hammer2 pfs-list" and then just
mount it somewhere using the label:
mount_hammer2 <hammer2-block-device>@<label> /somewhere
