This doesn't make sense. There is no default behavior if the property
doesn't apply. (Note the default is never computed; it is just behavioral.)

<overflow-position> modulates the fallback behavior after a fallback
position takes effect. We could add fallback positions for baseline
and stretch, and those could take <overflow-position>, but I don't
think it makes sense to apply <overflow-position> direction to baseline
and stretch.
