(1)The ways you changed are not footways they are highway:paths as described by the OSM wiki.

The wiki states the following:
a) "For multi-use or unspecified paths and trails used by a variety of non-motorised traffic the tag highway=path may be better suited."
b) "For urban paths which a designated for pedestrians only, use highway=footway."

The paths for which you have changed the pathway tag are not urban paths but wilderness trails.

Wiki page for Footway:
highway=footway

Wiki page for Path:
highway=path
