@Princeharris1993 We don't necessarily know that, there is nothing that disproves it as we have not seen it accomplished in Obito's dimension, but we have seen it in Kaguya's dimension.

I theorise that it is the Rinnegan that allows things/entities to be reverse-summoned from these dimensions; the Rinnegan enhances a person's summoning abilities, as they no longer require blood sacrifices, hand seals, scrolls and so on, and perhaps there is an underlying advantage being the ability to summon greater distances. And the Rinnegan having an impact on summoning abilities provides reasoning for Sasuke's ability to summon Garuda into one of Kaguya's dimensions, no other person who was taken into Kaguya's dimension showed the ability to do this (although it can be argued that they didn't need to because they're skilled enough without it). Moreover, this explains why Hagoromo was the one executing the reverse-summoning for Team 7 whilst the other Kage mainly funneled him with chakra, as he possesses the Rinnegan to be able to do so.

It would explain why Kakashi used Kamui instead of using a reverse-summon, and why Minato couldn't use Flying Thunder God, as they perhaps couldn't since they don't possess the Rinnegan. Also, it might be possible that Minato was avoiding Kamui just for the sake of caution, he hadn't seen this technique before at the time, and rather than risk it, he would steer clear from it.

It wouldn't be bad if Nagato had to summon the paths, as he's far, but not too far. He has to be close enough to create the chakra connections in the first place, and the paths of Pain wouldn't take long to get back to the battlefield. If they wanted to be fast enough, they'd ride on one of the animal summonings/send the animal path there by being thrown, so she summons every other path, like how they broke into the Leaf Village.

What's the explanation for the male Animal path still operating when he was in that toad barrier, if there was no chakra contact? This suggests there must be a stronger link between Nagato and the bodies rather than just chakra, otherwise any other Shinobi could use their own chakra to make their own dead corpse puppets. I tried to argue this earlier with the fact that the Rinnegan's visual prowess transcends dimensions, even into the afterlife. The fact that the Rinnegan appears to be projected into each corpse's eyes could show such a thing, although this is just speculation.

Additionally, yes repeatedly summoning the paths back from the Kamui dimension would be taxing on Nagato, but if we're talking about a battle, he would most likely be able to hold out longer against Obito due to his Uzumaki lineage for a considerably longer amount of time, we can't forget that Obito can become fatigued and chakra strained as time goes on. Pain's chakra rods may also prove a way to diminish his chakra supply, or to coax Obito into de-materialising.

I also thought of the fact that when the female Animal path was summoned into Ibiki's torture chamber with all the cogs and wires, the animal path remained operating and put Ibiki out of commission. When she did, it appeared as though they were reverse-summoned back into the battlefield in Konoha. This supports the earlier claim of the Pains having stronger bonds to Nagato other than just chakra connections and provides another example similar to Jiraiya's toad barrier, as she remained operational despite being in a hazy barrier or dimension of some kind. Granted this may not be on the same level as Obito's Kamui, but it is something to be acknowledged.
