I have a new proposed solution for this. 

First, the multicol spec will say that: 

  Column boxes are containing blocks for content that appear inside them. 

Then, GCPM will say:

  page 
  	Indicates that the page box is the containing block for the element. 
  multicol 
  	Indicates that the multicol element is the containing block for the element.

And, in an example say:

  The column box is the containing block for floats, so if an image
  naturally appears in the first column it will float to its bottom:

This way, we avoid duplicating normative text and still say things
clearly. Does this address the issue adequately?
