I feel picked by the second to last sentence in this answer to a question about what would happen if EM and QCD were spontaneously broken, which says
"In fact, there is a sense in theoretical physics in which confinement is complementary to Higgsing – it's the same thing in different ("opposite", "S-dual") variables"
to explain further why a broken $SU(3)$ gauge group could not be confining.
I'd like to see a further explanation of this. For example which of the weak/strong regime would correspond to the higgsing/confinement regime? Is it as I naively expect from the cited comment, the strong coupling constant that is used to establish the S-duality, or does it work via a more unified higher energy scale coupling constant? Heck, I'd just like to know in some more detail than just this comment, how it works.
