Ah an excellent question and the answer is... I have no idea. It's certainly a fan preferred couple and there are moments like Logan and Storm's bantering and Logan's protectiveness of Storm whenever she's in distress but that's no different from how he is with the students and the Professor. In general this version of Logan is one of the more gentle versions so it's more likely that he's just being nice. It's likely that whoever wrote that was young, younger people tend to see some gestures differently, depending on their age and understanding of love.
Honestly, it's not the only thing on this wiki that needs to be reevaluated.
