What he said

From the OP's perspective, if he/she does develop the two together, he/she only gains experience with what happens when the two are developed together (likely a relatively rare event) and not with what happens when the films are developed separately.

And again from the OP's perspective, it may be that the most valuable benefit he/she will gain from processing this film is knowledge and experience (rather than the shots themselves).
