BvS & Justice League Continuity Question

so at the end of BvS, literally the very last scene after Lois pours some dirt on Superman's grave (that's the spoiler tagged), it shows the dirt rise for like .33 seconds.

What the fuck did that have to do with anything in Justice League? I thought it was hinting that he wasn't really dead. I was honestly expecting the Justice League to open an empty casket or some shit and then that scene in the trailer for Justice League were Alfred goes "he said you would be back" would happen right when they needed him. I'm just confused dude. Anyone have any sort of explanation for this?
