They didn't talk, but decided to attack at the same time, because they realized that if senjutsu acts against balls, it means it acts against jinchuriki Ten-Tails. This means that both the balls and jinchuriki itself have the same chakra, which is vulnerable to senjutsu. By talk i meant the dialogue after and the inner thoughts/monologue during the attack

Anyways, senjutsu working against the TSB gave them the idea to try to use Senjutsu on Obito. There was never any correlation made between Obito's composition and the TSB's composition. The only explaination as to why or how senjutsu is effective was only given for Obito.

If the TSB are pure chakra and Obito has the same chakra then he shouldnt need the TSB to neutralize ninjutsu. Simply relasing some chakra would do it but that isnt the case so there are clear differences with Obito and the TSB. In fact, Minato and Naruto's giant Senjutsu Bijuu mode Rasengan didnt have any advantages over the TSB, it just wasnt nullified.

Any implications between the two were clarified in the databook and they dont support the TSB's being composed of natural energy and that should be enough to put this argument to bed.
