Here we describe how a switch works, as shown in the video below, there are first 2 switches (1st order, and 3+ order) I add a switch to with the segment "Journey VIP" and add another image.

Different switches are connected to different segments. If a recipient would match multiple segments, the priority is given to the segment they match first. So if a recipient matches both 3+ order and Journey VIP, they will receive 3+ order because that switch comes first.
