Kelly, beg my pardon, but your explanation makes things even worse for me:
"are right next to each other (and collapse together)."

Either they next to each other - either they collapse (overlap).

Let's put aside task of HTML rendering on Moebius
stripe surface. The only situtaion when 
"If the top and bottom margins of a box are adjoining" is then 
box has zero height.  Why not just say so? 

It remainds me definition:
"That spot where human back starts loosing its name".

But I suspect that meaning of the original phrase[1] in CSS21  
is completely different this is why I am asking....
