Unsure how, I understand that it takes rounds to clear away the imperfections in the machining and because of those of those imperfections a new barrel is prone to catch corrosive materials and debris until smoothed and its the cleaning part of the process that just prevents any of that build up damaging the surface.

I did 3-5 shot groups before cleaning on my remington 700 but the manner in which that is shot aids that, was a long winded approach continuing that to 50 rounds though and took a good part of an afternoon.... Accuracy did improve to sub MOA (still to concentrate on grouping vs burning in) and alot more crap came out in the cleaning process than with a "used" gun when you consider it was cleaned 10 times on the day and add that up.

There seems to be merit but is it more about you wasting 50 rounds of ammo and 50 rounds of the life of the barrel so you have to buy more lol

This is the official breakin procedure from NEA, I just used a bore snake with hoppes every five rounds or so while adjusting the scope.
