I wouldn’t want to gut such a pivotal moment in TLJ. The scene would barely make sense without that revelation, it’s such a key moment that shows how unprepared Rey was to face Snoke, and that things aren’t going to go the way she thinks. And even if you remove the line the rest of Snoke’s dialogue still implies he knows exactly what’s going on, so it doesn’t really help TRoS’s case, if anything it heightens the question of whether Snoke knew of the dyad.

It’s clearly shown Snoke is extremely powerful in TLJ, he mops the floor with Rey and effortlessly probes her mind. There’s no need to ‘explain’ how he can do it without dying. The effort would kill Rey, it wouldn’t kill Snoke. And as I said, bridging minds and Force projection seem like two completely different powers. Kylo’s “the effort would kill you” simply foreshadows that extreme uses of the Force drain your life energy. Snoke was probably more powerful than Luke, but even if not it’s easy to assume Force projection might take a higher strain than a bridge of minds.

The dyad is barely explained, Kylo describes it as “two that are one”, and Palpy says it’s “the life force of your bond” and “a power like life itself”. So TRoS doesn’t even directly state that being a ‘dyad’ means having force Skype calls and teleporting objects. Kylo says the power of their dyad will allow them to kill Palpatine and take the throne, which wouldn’t make sense if all there is to it is the mind connection stuff.
