I don't know about boxing but Swordsmanship is pretty clear when it comes to no touch AdCoC..
The Roger and Whitebeard AdCoC clash, if you remove Roger's Sword alone, nothing changes, if you remove both Roger and Whitebeard's weapon, again nothing changes, if you put baseball bats in both their hands, nothing changes the result always remains the same..
That's why Roger and Whitebeard's clash was a no name clash, you'd have a point if it was paradise Totsuka vs Roger's Divine Departure, those are connecting and are Swordsmanship, in fact they are CoA attacks, not AdCoC..

"if you put baseball bats in both their hands, nothing changes the result always remains the same.. " nah those baseball bats break, they can't handle theweight/might of their haki, supreme grade blades can though. you're just repeating yourself though so I'm not gonna bother re-explaining in a circular argument
" you'd have a point if it was paradise Totsuka vs Roger's Divine Departure, those are connecting and are Swordsmanship, in fact they are CoA attacks, not AdCoC.. " you're acting like you couldn't use adcoc with those moves? that's the example i gave you but you seem to just ignore it for your convenience.
if two people coat a barrier around their sword defensively like hyogoro explained, in order to not cut the opponent but create a shockwave instead (like with kamusari), what happens when they meet in contact?
I'm just seeing nonsensical lines of argumentation from you
