I think the primary factor is going to be how much of the material doesn't require the same length of time. The translation from printed to moving medium allows for some material to naturally not take up as much time.

An action sequence that takes a whole chapter or more in the manga might only be a few minutes in the anime, simply due to the different natures of the media. In particular, these final arcs involve a lot of pages that are sweeping shots or sequences that shouldn't take up much time in the anime. Several pages of images might only be a few seconds of animation, since a manga naturally requires more time to convey the same material.
