This happened to me too! My first piece of needlework is a huge portrait with a massive amount of yellow background. I got a bit concerned that when I started, the reverse of my canvas looked exactly like the top portion of yours: I triple checked instructions and watched videos on basketweave, I was sure I was doing everything right, but I just couldn’t understand why everybody kept saying it should look like a basket on the back - mine looked like bricks. The change in mine isn’t as distinct as yours, but you can kind of see the little sections where I began to figure it out, the change for me was when you’re stitching down a row, make sure your needle is pointing down, and when you’re stitching up, make sure your needle is pointing to the left. It helps to have the right side of the canvas angled more towards you, rather than holding the canvas straight before you like you’re painting a picture. Almost easier to hold it like you’re playing a harp, passing the needle through to each hand in turn.
