Found this regulator says multi gas supported?

I found this regulator at my local home brew supplier and I was wondering if anyone has any experience with it.

One question is how is this able to support co2/nitrogen/argon/beer gas blends?

From the specs:

“The Taprite regulator has a one year manufacturer's warranty. The bonnet is made from industrial zinc which can handle higher pressures. The regulator is approved for CO2, argon, nitrogen, beer gas, and beer gas blends.”

It can apparently manage CO2 or Nitrogen - or presumably beer gas, but it can't do "blending" as there's a single stem.
Given that most beer gas is sold in cylinders with CGA 580 valves, you'd have to swap the provided CGA 320 stem to switch...

Cheers!
