"extent" means the logical height, so, yes, it means 'width: min-content'
and 'width: max-content', but only when in vertical writing mode. :)

No, the grammar is correct here. Maybe s/same/equivalent/ would help though.

Well, you have to understand that the min-content sizes of an element
are used and need to be defined even when not explicitly specified,
as they're part of the auto layout algorithms for e.g. tables and floats.
So keying off specified 'width' or 'height' values in these definitions
is not useful.

:/ Need to do a massive editorial pass over all the specs, the auto-linkification
of values is really a problem... it's wrong any time there are multiple uses
of the same keyword. Like 'auto'. >__<
