Yep. He's been on record saying that they've spent a lot of time working on penalties. I doubt there will have been surprises when they were dished out. The occasion, the quality of the other keeper... there are things that you can't practice for. One team, and some players have to be on the losing side in this format, it can't be another way.
Also, some comments have been made on the fact that the penalty takers who missed were young and black... it will be hard for them over the coming weeks for sure, but to have a manager who looked at their quality first and believed in them, that's gotta count for something.
