Multi camera application with Multi Camera Adapter Module V2.2


I’m interested in a multi camera application where I’ll want to control the cameras individually, so I need them to be non-synced with each other. I was looking at the multi camera adapter module V2.2 at Arducam Multi Camera Adapter Module V2.1 for Raspberry Pi 4 B, 3B+, Pi 3, Pi 2, Model A/B/B+, Work with 5MP or 8MP Cameras - Arducam

It says “Cameras work in sequential, not simultaneously”. Does this mean I wouldn’t be able to start the cameras individually at different times? Would the cameras be forced to capture frames in a sequential order? I’d be grateful for further explanations on how this module works and what it does.
