C`mon, guys, I think you're underrestimating Tsukuyomi or namely its feature of altering the victims time perception. There's no guarantee that the Tailed Beast can immediately sense that the Jinchuriki got in genjutsu and also immediately break them out of it. I mean, even a second of lingering would end up in Jinchuriki receiving severe phychological damage, since a secong in the real world can become at least as long as several days within Tsukuyomi. And, judging by B's examples of Gyuki breaking him out, there actually is a minimal time of the beast lingering to notice the genjutsu and dispell it.

P.S. I completely forgot that breaking from Tsukuomi isn't like dispelling a regular genjutsu, so there's even no guarantee that the beast is going to break its jinchuriki out even if it notices the genjutsu.
