We wanted to make the patches smaller, it's the main reason for this separation. Patches should be divided by function, not arbitrarily in order to decrease size. Splitting like this makes it harder to see the whole picture, to search for identifiers, etc. The right way to make these patches smaller is to remove unnecessary features.
