[css-exclusions] interacting with floats

I was reading up on the floats section of CSS 2.1 [1], in order to understand better how they interact with Exclusions. The exclusions Editors Draft says this:
#Exclusions have an effect on the positioning of floats as they have an effect on inline content. Therefore, in Step 2-B, floats will avoid exclusion areas. [2]

OK, so floats will not overlap the exclusions in their ancestor's exclusion context (I think I said that right). 

But where do the floats end up? The floats section of 2.1 says this:

#A float is a box that is shifted to the left or right __on the current line__. [so that's good] ...A floated box is shifted to the left or right until its outer edge touches the containing block edge or the outer edge of another float. 

Do we need to say somewhere that an exclusion edge also stops a float from shifting farther to the left or right? Or does it? If the exclusion has 'wrap-flow: both', with enough room on either side for the float, does a 'float:right' float stop shifting over once it touches the exclusion (and the end of that segment of line box), or does it move to the other side to be as far right as possible within its containing block?
