I would not try and make assumptions based on the different filing strategies of each lawsuit.
I think the weakest part of Goodluck is the PI. The standard needed for a PI is proving that the plaintiffs will suffer irreparable harm without stopping the behavior of the defendants. Since some GL cases will be processed, you can only show that SOME of them will be harmed. Its tricky, and to some extent, already argued and lost.
That is not saying GL doesn't win. I expect GL and Goh to cause action on cases that would otherwise have timed out. And then some preservation of visas will be needed. That is likely to be needed for Goh plaintiffs and certain to be needed for GL.
In the same way, Goh could win without a summary judgement, but as I said, is likely to need a preservation of visas.
