Even though I told you don't ask me why.. you're asking me why. But I'm a good donut so I went back:
They dont have to press BOTH keys to press space, they just didnt have a spacebar key that is the correct size to fit, so they put those 2 random keys on instead until they get a permanent keycap set that all fits.
Shift is A, Caps Lock is Z, Control & Backspace is spacebar.
Don't ask me why, I just searched the image and found the reddit thread that this post is riffing from and got my answers
bruh why would they make spacebar a two key combo. That is literally the most used key

thanks. For the record, you are a great donut
Worthy of the title Princess Donut, even.
Ooohhh, keycap issue.
