2.7.7: When Rand and Mat are travelling to Caemlyn in TEOTW, why does the scene with the scarves happen twice?

In TEOTW, after Mat and Rand split off from Thom in Whitebridge, they travel to Caemlyn alone. During that journey, there are two scenes which are exactly the same, even with almost the same wording. These two passages are [TEOTW: 31, Play for Your Supper, 382] and [TEOTW: 33, The Dark Waits, 416]. In both descriptions, the farmer asks Rand and Mat who they are running from. Then he says something about wanting to help them, but he can't because he might get in trouble for helping strangers. He feels bad, and offers them two woollen scarves, which he pulls from his pocket. He explains that he knows it isn't much, but they are his sons' scarves, and that's all he feels he can give them safely. He wishes them luck.

Is this an error? What's going on here?
