It makes perfect sense. I'll explain.
What I was talking about is the ability of mirrorless to focus anywhere in the frame. DSLR's can't do that because they have a limited number of focus points usually in the central area.
So. With mirrorless I have compositional freedom and I can have, for example, a face anywhere in the frame and still be able to AF (or MF) on it. You can't do that with a DSLR with its focus points all clustered together in the central area and poor if any MF aids. The only way to do it is to alter your composition or shoot with an available focus point and then crop the picture to get the framing you wanted.
Focus and recompose is not the answer for me as it will lead to the point of focus moving. It's only the answer if the photographer is willing to accept the fact that the point of focus will not be where it originally was or uses dof to cover the fact or just doesn't care. All are valid I suppose
