I seem to be the only one not completely convinced it was for Jesse's benefit, though. Or rather, not entirely for Jesse's benefit. It think it had something to do with Walt. That is to say, Jesse benefits, clearly, but what Gus' end game seemed to be about was Walt's reaction. He isolated him in the lab, refused to speak to him, and with the "attempted hijack" began to perhaps change the dynamic of the pair when Jesse returns (the whole "I've got two jobs now" thing).

I'm not sure where it's leading, maybe it's to set up (again) Jesse against Walt in some way.

And maybe I'm just overthinking it.

You're not overthinking it. He just drove a wedge between Walt and Jesse AND gave Jesse another job to occupy his free time with.
