Can you tell me a little more about what that means? Does "or visual"
mean that adequate clearance exists when both planes have visual
contact and miss each other?


Only one aircraft has to sight the other one to use visual separation, the
other one just has to be informed that visual separation is being used.
There is no minimum distance in visual separation, it's whatever the pilot
is comfortable with.
