And the last column's left edge will be offset 400px from the multicol
container's left content edge, i.e. it will be outside the multicol's
content box. Not that I see a problem with that, though.

I can only speak for Presto, but the reason for this behavior is that
Presto implements the 2009 CR, where correct behavior was to reduce used
column-count in situations like this.

That sounds like correct implementation of the 2011 spec.
