I think they ARE running out of ideas now. They covered this subject in the first season in "There but for the Grace of God". I don't think anything was added here. The room full of Carters wasn't as amusing as it could have been, and Martouf and Dr. Fraiser only had brief parts.
How did the 'black uniformed' = 'bad guy' SG-1 team know so much about our reality. How did they know that the ZPM was on Atlantis, still worked, and hadn't been destroyed? It was a extraordinary idea to save their Earth, with many chances of failure and taking rather a long time if it was currently under attack.

Episode Summary from SciFi.com:
SG-1 returns from a mission early, accompanied through the stargate by a weird sound and a flash of light. Then, during their debriefing with Gen. Landry, they reveal that they were exploring a different planet than the one they'd been assigned. Moments later, the stargate activates again — and a second SG-1 team steps through.
Dr. Lam determines that, genetically, both of the Mitchells, Carters, Daniels, and Teal'cs are exactly who they claim to be. Because the second group arrived on time and from the correct planet, Gen. Landry guesses that they are the "real" SG-1. Carter then theorizes that the other team comes from an alternate — though very similar — universe. Under questioning from their counterparts, the duplicates explain that their Earth is about to be invaded by the armies of Origin. Unfortunately, because an astronomical fluke — the passage of the stargate's wormhole directly through a black hole — seems to have caused their arrival in this universe, sending them back to join the fight in their own universe won't be easy.
Before the two Carters can find a solution, the stargate activates again, and out steps a third SG-1 team. Within hours, more SG teams from more alternate universes arrive, until more than a dozen SG-1 units are roaming the base. One of the teams even contains alternate-universe versions of two old friends that Carter, Daniel, and Teal'c never expected to see again: Martouf and Dr. Fraiser. Because both died several years ago in this universe, their appearance is a bittersweet shock for everyone who knew them.
The troop of Carters now working to solve this astrophysical conundrum soon brainstorms an extremely complex solution that involves — among other details — flying the Prometheus to the black hole and detonating an explosion inside the singularity to seal the multiversal rift that has developed. This will prevent more teams from coming through — but it will also strand the new arrivals permanently on this Earth. While Dr. Frasier, in particular, pleads with Landry to give them time to find a better solution, he reluctantly decides that his universe must come first. He orders his own SG-1 and the first duplicate team to take the Prometheus and carry out the mission.
As soon as the ship reaches the singularity, however, the second SG-1 team seizes control, locks the original SG-1 in the brig, and redirects the Prometheus onto a very unexpected course. To figure out what's really happening and escape, the original SG-1 team must now outwit their toughest opponents yet: themselves.
