Depends what spec the ports are. I just have a 7 in 1 adapter that plugs into one port.
Also the ports on the Mac are TB3 not USBC

@Slottr Agreed.
To the OP, I'm pretty sure you can find some adapter that will only use a single connection. One thing that comes to mind if your adapter does use two, that it might be for max bandwidth OR charging abilities.

one of the reasons for adapters like this is power delivery and circuit separation. typically you'll see adapters like that have 2 ports because there will be a USB-c pass through port for charging and the other port will break out into the other USB, hdmi, sd card reader etc isolating the ~100watts at 20volts of power over USB-c which you absolutely don't want going into a USB-A or SD card which only need 5volts.
some adapters will have isolation circuits built in but many companies prefer to just fully isolate the USB-C to C plug so they never have to worry about fried other devices.

It's most likely so you can make use of all the ports on the adapter at higher speeds, since you could probably easily saturate the bandwidth of one USB C with a display and couple of peripherals and drives.
