Could someone tell me where this path begins?

I took this screenshot from a streamer today and I really like these paths...but the problem is I don't know what square is the path...if I'm making any sense. Like, where are the borders of one path square? I can't tell!

It's the purple rectangles, 99% certain.

I don't think this is right. The pattern looks like it starts one more space to the left of the purple so it splits the top orange rectangle in half and goes down to the blue rectangle. I'm pretty sure you could always visit that streamers dream address to see what the pattern is though, or ask them and they might reply.
