There really isn't any lapse in logic here, per se.

In seeing the prototypes, both Ruby and Sapphire were both feeling the same fear, sadness, and responsibility. Both almost unfused because they were torn about who to blame whether it was them or homeworld (also finding shattered friends forcefully fused together), but found common ground as they'd rather end their fallen allies' suffering and take responsibility, and stayed fused.

In Keystone Motel, both of them experienced the same thing with Pearl's betrayal, that being that they both felt, ya know, betrayed. What tore them apart was their inability to find common ground, as what they did with the prototype debacle.

tl;dr It's easier for them to stay fused when both of them are feeling the same distress and finding a common ground for the issue than feeling the same distress but both have different views on how to deal with the issue.
