That’s one way to resolve it, but I’d also add:

     Absolutely positioned content is not clipped at column boundaries.

("Absolutely positioned" also includes `position: fixed`, right?) 
Perhaps this sentence not necessary (not clipping is the default) but I 
like having things written explicit in specs.

I think the union of in-flow, floating and absolutely positioned content 
covers everything. (Except the root element, but by definition it can 
not be *inside* a multicol ancestor.)
