He seems confused.
Mast foot is your foot closest to the mast (front foot). what he's referring to is mast base pressure. They are two different things which will produce different results when described properly to a learner.
Might be a European thing. In German mastbase is called "Mastfuss" which translates to mast foot, and I think the French call it "pied du mat", so this seems to be the logic he refers to.
Obviously we're all talking about the place where the mast meets the board (and no, I don't mean the board's nose in the event of a catapult).
Pressure here can be a very useful tool. Calling it bad is clearly oversimplifying things.
