Did he study or observe Wells' life? Does he have he's memories for a strange Speed Force law? He lived as Wells and then knowing he's fate escaped in the moment Eddie killed himself making it appear as if he was erased by time? Matt Letscher posted about this on his twitter during the hiatus, actually, though he said that we'll get an explanation in one of the episodes.

If I had to think of an explanation, it's that when he traveled with Barry to 2016 he got memories of the "Wellsobard timeline", so that he'd 'fit' in the new timeline while still having his "prime time" powers and personality.

That's how it often happens in DC Comics: after a person is "adjusted" into the new timeline, they slowly adjust to the "new" memories. It happened to Barry Allen after her subverted the Flashpoint (in the comics, creating Prime Earth), and it's now happening to New Earth Wally West and New Earth Superman as they settled on Prime Earth after "Rebirth".

Basically, as he continues to stay in the "new" timeline, especially after traveling through the Speed Force (remember those many images you could see in a blink of an eye when Eobard brought Barry to 2016?), he gets memories that Eobard of that timeline was supposed to have.
