The part I was quoting is in the next clause.  The full sentence is:

   This is true even in the presence of floats (although a box's
   line boxes may shrink due to the floats), unless the box
   establishes a new block formatting context (in which case the
   box itself may become narrower due to the floats).

In my case, the box has overflow:hidden, so establishes a new block formatting 
context.
