  Still, I think my

Not really.  One looks-up a key and supplies a default value if not found.
The other, set.get(), doesn't have a key to lookup.

A dict.get() can be meaningfully used in a loop (because the key can vary).
A set.get() returns the same value over and over again (because there is no key).
