hypothetically Yes from all the information we have from the show the gates would have the same address.

As for points of origin we don't know how planets/moons get them or at least get assigned origin symbols. (unless someone can correct me) but it would most likely be the same.

supporting points: In SG1 there's an episode where Sam blows up a star using a stargate. the stargate was launched from the Ha'tak. this was not the gate from the planet that had one before the star blew up, as it was used by a goa'uld to get off the planet before the star blew. This supports the fact that they would have the same origin due to them dialing the gate quickly.
