It is correct; the binary is AGPL, and Snap is a binary distribution method.

Nope, the binary is under both licenses. Just because they are compatible doesn't mean you can ignore the terms of one of them.

I sometimes “editorialize” license names for Lunni Marketplace, too. [1]

I think it’s fine: the binary is under both licenses, but one requires you to publish a notice and the other requires you to publish a notice and all source code for both parts. Since you want to know what “license burden” you’ll have to bear when you’re looking for an app in a distribution platform like this, I think it’s fair to just specify the more restrictive license.
