It is a pretty impressive demonstration of the error correction built into QR codes.
That's so great we can plaster logos in the center of it without any reasonable considerations and it would still work, so that's now abused by many apps and services. No, they weren't designed to do that, it's just a random obstacle, like a dead bug, that doesn't obscure the reading too much. Trully impressive.
While not strictly a QR code, I always liked that the Dolby Digital data between perforations on a film strip had a tiny Dolby logo at the centre.

Error correction is always used, in case the QR code is damaged in a way that leaves a valid-looking QR code. In this case, it likely fixed any accidental misstitches. I don't know how to check how much was used, but thanks for the afternoon project!
