Why did they pick it?

It's automated. In this game, the player chose a draw. There was a clearly winning play. There was only one clearly winning play. So the algorithm picked it. There's only one clearly winning play.
The problem is that the algorithm was not programmed to understand the reason there was only one winning play was context-dependent. Without that context, there are two moves. So it just needs manual human intervention to remove it from the puzzle pool.
Actually, I kind of like this puzzle. It's very common for me to see what appear to be 2 equally good solutions, but knowing that there is always only one best solution** I look again. In this case, you have to think to look at the game history. The only unfortunate thing is that the rating on the problem does not reflect the difficulty because it is easy to get the right answer without seeing the trick. But there are a lot of problems where there are only 2 plausible solutions, so lots of people can get it right just by guessing. What would you all think about a problem that hinged on the fact that despite appearances one side can't castle?
** This is not strictly true - I've noticed while doing the simple puzzles on Puzzle Storm that there can be more than one way to delivery checkmate and the system is set up to handle it.
