I would only ever raise that river as a bluff. You have the 2nd nuts, don't bluff. But you're right it does seem weird.

The flop raise is good I think. Lot's of turn cards can freeze you up so I like getting it in there. And plenty will call you too, since there are so many draws on the board. If he has a pair of 10's he could put you on the potential heart draw. Or maybe he himself has the heart draw or straight draw.
