Default watching type inaccurate about when notifications are send

Recently did I receive an E-mail regarding a post in this forum I never participated in.

Looking closer at this did I notice that someone linked a post I made here in a reply which seems to have triggered the notifications.

That said does the default Watch setting say that you only get notifs if you either get mentioned or someone replies to your posts. It does not mention that linking to a post of yours also send notification. Does this somehow count as “Replying to you”?
Because I feel like this should, when possible, be changed to either not trigger notifications in this case, or mention that also linking to your posts counts as reply or similar.
