Seeing as he's playing immediately following Miami (where he has points to defend), because he's trying to get his ranking up by playing smaller events (and he is NOT a top player, so this is a perfectly reasonable tactic), this was a smart choice. The stupid choice would have been getting his foot broken again, which is apparently what some people would like to see
One can argue that he shouldn't have stayed in South America for so long. I say that he went down there ranked near 50 and left ranked around 30. Sounds like that was a pretty smart decision to me.
If he's still doing this when he's ranked 10 in the world I will be happy to criticize him.
