I think? But Jergal has always been a little weird.
All D&D gods are a bit weird. Mystra died three times, and is technically dead but not really as she still rules over magic. Similar to the Raven Queen who also died but not really as the Shadar-kai still work for her and she can sometimes be seen in her castle almost like a ghost haunting the place, etc. There's a lot of really vague weirdness going on with D&D deities. None of them seem to ever really die for good...either their essence reforms over time or there's some shenanigans going on all the time. It's best to think of godhood in D&D as a one way road. Once you get it you won't lose it.
