That seems compelling to me as well, but I still have questions.
Presumably this only occurs when there is still space left in the
element, right?  That is, it would only occur if the overflow columns
are due to column breaks, not normal overflow (as that only happens
when there's a constrained height and the content fills that height).

What if there is normal content between the column-breaking elements
and the column-spanning element?  Would this create a new column row
just for that content (with the content balanced across the columns),
followed by a new column row for the spanning element?

It seems like perhaps this feature (column spanners in overflow
columns still showing up in the main area) should instead be a
function of the column-overflow mode.  With 'column-overflow:inline',
overflow column spanners don't span at all.  With
'column-overflow:block', they do span, in the way you describe.
