It's all about contact pressure. Tin-plated connectors use higher
pressures to help "wipe" the oxidation off for a reliable contact.

So, if you put a gold pin into a tin socket, the excess pressure
will wipe off the gold, exposing the base metal to corrosion.

If you put a tin pin into a gold socket, the insufficient pressure
will fail to wipe the tin clean, and it will be unreliable.
