Shield swapping in combat is cheating.

You dont see the menu when inspecting, that looked like ALGS and the people playing there is extremely good and spent countless hours practicing fast armorswaps, same you can swap to an empty one 😉 I died to that sooo many times.

But yes there are swap macros where people  swap where menu just flash on your screen (this is however cheating), but this as its an inspect so you wont see his menu, might actually be legit just because its from ALGS so you know most of the people in there are capable of doing insane plays.

Edit: Observer/Commentator cameras dont see maps and menues when inspecting players, same as when you die and you inspect your killers playcam, or your buddy while waiting for pickup/spawn.
