I don't think that's true/maybe that comment is misleading. Tombstones
AFAIK will be propagated by hints, and the hint system doesn't do anything
to check if a particular row has been tombstoned. To the node receiving the
hints it just looks like it's receiving a bunch of writes, it doesn't know
they are hints.
