The single/double checkmark is used with Signal's client as well. When you're sending unsecured texts, you get a single checkmark when you send it; when you are sending encrypted messages, a lock symbol and a single check when sent, and a double check when received.

Especially when there's a key change warning afterwards. I think this is still the correct interpretation in Signal proper, but who knows at this point?
