If you have read the other documentation on categorizing appointments by status, then you'll know that all appointments start out in "Open" status. After that, an appointment can move to any other status and be found in the respective list for that status. Appointments can be opened and thus changed to Open status from any of the other statuses.
If you use appointment categorization correctly, then Open should be synonymous with Upcoming. If you don't accurately move appointments after their appointment date to the respective status (either No Show or Completed) then your Open appointments may include some past appointments as well.
