I’m just assuming that the viewpoint switches sides at that point, but that’s a confusing choice to make. Perhaps the artist thought they were following the 180 rule by keeping each character to the same side of the frame, but in this case that would be a bad interpretation of the rule. Here the entire premise requires that they walk past each other, so the viewer expects them to switch sides of the frame and is disoriented when they didn’t. Or maybe the artist actually intended that they nonsensically switch directions after bumping each other? I suppose we can only guess.
When I was in highschool we edited that file in the programming lab. Wrote an auto running batch file to replace it when the floppy disk was inserted and managed to sneak the disk into every machine without the teacher noticing. The computers where arranged around three walls of the room, and we knew that his standard procedure at the end of the day was to go to each one and issue the shutdown command, then circle back around to power them down. That afternoon when he turned around he must have been greeted with his own employee ID photo grinning back at him around the room in 16 color bitmap glory.
The next day he sternly waved us over the moment we walked in, then just laughed, said “put it back,” and waved us away. He never bothered to even ask how we got ahold of his employee photo from the school network.
