Yeah, I got the same impression, and I hope Locke will draw the same conclusion. Patience tried to make both Sabetha and Locke believe that Locke = Lamor Acanthus, and also that Lamor's beloved had the same red hair Sabetha has. Now, even provided those two facts are true (considering her main motivation is to fuck with Locke, that is highly unlikely), it kind of misses a very important point: young Locke fell in love with Sabetha the first time he saw her.

The first time he saw her she had her hair hidden - he was already completely smitten by the time he caught the first glimpse of her red hair.

So, yeah, my take on it is that Locke was always a weird little kid (who falls in love at six years old? without growing out of it?), and odd as it is, his feelings for Sabetha probably aren't related to Lamor Acanthus. Probably. Like I said - the falling in love at that age is a bit strange, but that's Locke for you.
