I'm no expert, but I would bet that the WAHP shot was done that way so that the film speed would match up with the frame rate of television monitor playing on-set.
Sounds logical. On the other hand, we have a lot of real monitor shots done in 24 fps. I've read somewhere, that it was common practice to rather match the refresh on those CRT's to film rather than vice versa.
And this doesn't explain at all the reason behind the unusual frame rate in "Identity Crisis".
