Can someone explain what's the purpose of this remapping?

Is this for MacBook Pro models with a Touch Bar, or is it something else altogether? In the former case, a better title would be "Map Escape to Caps Lock".

I don't understand it either. I have mapped caps lock to some command launcher/window switcher, which spares me pressing two keys.. Esc is even on the same side as the keyboard..
