Whether or not that >character is 'z' is a different issue. Section 2.1 indeed says that %7a and %7A both represent the same octet. However, they are not therefore guaranteed to be the same character regardless of encoding, because there are encodings where a single byte is only representing part of a character, and/or can be used in representing different characters.
