Inconsistent example regarding Request Object in automatic registration

[cicnavi]

In 12.1.1.1. Using a Request Object description of aud claim says that it must be OP's Issuer Identifier URL.

aud
REQUIRED. The Audience (aud) value MUST be or include the OP's Issuer Identifier URL

In example in 12.1.1.1.1. Authorization Request with a Trust Chain for aud claim is given:

"aud": "https://op.example.org/authorization-endpoint"

which seems as if authorization endpoint is used.
