This screenshot is a little bit hard to see, but from what I can tell:

°RA is pointing at °R and °C
°C is pointing at K and °F
K is pointing at °R and at °F
°R is pointing at °F (and the other gun isn’t aimed at anyone in particular)
°F is pointing at K and at °C

Emphasis disproves your claims, sadly. Perhaps there was another way to label them to make it fit, but that’s not what was done here.
