curl uses getaddrinfo() to resolve names when built IPv6-enabled (if c-ares
wasn't specified at build time) and that returns the addresses in an order you
decide with the /etc/gai.conf file (on Linux). curl will simply create the
socket using the IP version that matches the address it will use. In your
case, getaddrinfo() clearly returns IPv4 addresses before IPv6 ones.
