The tag motorway=yes is used to describe motorways that have motorway traffic rules and access restrictions (e.g. cyclists and pedestrians banned). Depending on the country, this may imply various access restrictions and other road properties.
Usually, motorway=yes is simply implied by highway=motorway, and motorway=yes needs not be explicitly tagged. However, there are cases where motorway rules apply but highway=motorway is not used. Notably, motorway ramps tagged with highway=motorway_link typically have a part where motorway rules apply (after start-of-motorway sign or before end-of-motorway sign) and a part where motorway rules don't apply (before start-of-motorway sign or after end-of-motorway sign). This can be mapped by tagging these respective parts with motorway=yes and motorway=no.
Motorway versus motorroad
An abandoned older proposal for this key proposed more extensive use of motorway=* beyond motorway links and also proposed a separate value for substandard motorways, but the key is not used like that nowadays.
