Question on tag filtering for wheelchair

I was looking at the wheelchair routing tag filtering and noticed that it accepts sidewalk=both, sidewalk=left and sidewalk=right on ways, but rejects the sidewalk=separate tag AND highway = [trunk, trunk_link, primary, primary_link, secondary, secondary_link, tertiary, tertiary_link, road]. Does the algorithm take into account the sidewalk:both=separate tag as the OSM wiki suggests to use this tag on roads when a separate sidewalk network is mapped on both sides. Will the algorithm still avoid these, or will it only take the “sidewalk=seperate” tag into account.
