With eyes located on opposite sides of the head, rhinos don't have good binocular vision like humans and other primates do, and also lack color vision. The rhino probably thought that the buffalo was another black rhino and possibly threat, however when he got closer he seemed to change his mind on attacking the cow. Probably the rhino realised that the buffalo cow was not a threat and proceeded on his way.
