Ideally, AJ has the title and Orton isn't even near the main event, but that's just doing fantasy booking pretty much. I don't think people are flocking to their televisions or to arenas to see Orton/Corbin or Orton/Zayn.
They are less likely to turn it off for those programs vs giving them a Jinder program.
Especially in the case of Sami as fans will get on board with the push for an underused favorite. Just look at how hyped people got for a Bray push when it finally happened despite years of misuse.
As for AJ. The logical program coming out of Mania was to do Orton vs heel AJ. It wasn't any kind of crazy fantasy booking to put that together. AJ felt shafted out of the title, so it made sense for him to go back after it once he was done with Shane.
My guess is they mistakenly thought they could draw that out until Summerslam, but that assumed people could stomach Orton as champ for that long.
They then turned AJ face and put him into a weak mid card feud with KO, and now I really have no idea what they actually want to do on this show.
