Maybe it's the simplicity of the art style. Big round heads, small body's, usually posed standing, everyone is same shape, dialogue focused comedy. I don't know, I'm just spit balling here.
Edit: having a look at the website the comic is publishes you are right. Hell you're even more right today since the last two comics are almost exactly same. Same characters, same positioning, same actions. The only difference is the dialogue and the facial expressions.
I imagine the artist has a bunch of stock art he just cuts and pasted in to the comic so he doesn't have to redraw something he's already drawn.
