Having your female partner fall from a lift (or hurt on another pair/dance element) can be a difficult experience in itself. The men know what kind of risks their partners are taking and they're trained, at least in theory, to try and break any falls.
Not that it's at the same level, but Marinin reportedly had a much harder time getting over the 2004 Skate America fall than Totmianina did.
I saw that in an interview, too, but Totmianina said it did not bother her as much because, having had a bad concussion, she did not remember much of anything about the fall.
I really don't think we can have confidence that we can correctly infer what either the skaters or the coaches were thinking in the KnC. People who know the cameras are on them are not going to be reacting normally.
