Man page issue about ipv4 and ipv6 overriding

[Alexxz]

I did this

man curl

   -4, --ipv4
          This option tells curl to resolve names to IPv4 addresses only, and not for example try IPv6.

          See also --http1.1 and --http2. This option overrides -6, --ipv6.

   -6, --ipv6
          This option tells curl to resolve names to IPv6 addresses only, and not for example try IPv4.

          See also --http1.1 and --http2. This option overrides -6, --ipv6.

I expected the following

I expected that -6 option overrides -4 and --ipv4 options but not itself
