I assume written description is of a reatreating De Ashi Barai and by davancing the foot they are referring to the direction of movemet i.e. backwards, this would make sense.
Looking at both versions I think there are some editorial and some translation problems with the technique description.
Generally speaking one can apply deashi moving forward or backward. When moving forward you push (not really unbalancing per se) uke so he steps back on his left foot which leaves his right foot forward and exposed. As you maintain the pressure and uke begins to lift their right foot, you have an opportunity to sweep.
I think this is what the author was trying to describe. Not that uke advances their right foot but that the right foot is left in the advanced position as a result of the left foot being withdrawn.
This is when it gets weird. The description of the finish where tori opens to the right to clear a path when sweeping with the left foot is really only necessary when applying deashi moving backwards, not forward as described.
Neither do the sequence of photos seem to follow. I suspect that two different applications of deashi and two different photo sequences have been badly translated into English and then badly edited into a single description.
I would not set my hopes too high on learning to do judo like Mifune by reading this book.
Good judo comes in the dojo by feeling the motion and mass and momentum. Books can add some context and information but one doesn't learn judo by poring over dusty old volumes of badly edited mistranslations.
