Once they are deployed, they aren’t connected to each other anymore and there is no way to perfectly align two satellites again. I’m assuming they don’t even have RCS they could achieve accurate translational movement with. If you push one satellite against another and they aren’t perfectly aligned so the thrust vector goes trough the combined CG, they will start to spin immediately.

I agree that alignment would be a massive challenge. There aren’t even cameras on the satellites to help with visual alignment. There’s also the possibility of damage from the pushing or the ion exhaust, more so if the imperfect alignment sets them spinning
