Can someone help this make sense?

I saw this post somewhere on reddit. I know that pi cannot equal 4, but looking at this makes it visually counterintuitive. Can anyone help me understand this intuitively?

Edit: Thanks for the replies, I understand it now. It turns out, I simply needed to visualize the lines after a large number of repetitions. My mistake was trying to visualize the line after infinite repetitions and forgetting that x approaching infinity isn't always equal to infinity.
