It looks like it makes Jiraiya's fight with Pain its own arc, which I think is reason enough not to act follow it; Sasuke and Itachi meet twice in that time and Tobi starts fighting the Konoha ninja, which isn't resolved until the following "arc". That's too messy to manage just to appease the supplementary books.

Note the mission names somewhere, but don't go beyond that.
