Kerstin, I don't think it's about 3 degrees or so. Or are you talking about 100%? I find that exaggerated, whether it's holding the camera slightly crooked or not aligning the paper exactly in the scanner.
But take a close look, I think you're confusing something: these are different sections, the narrower street on the left is not visible at all on the blue one, at least it is also blue... Just compare dead end and houses ;)
