I don't think it's useful to think of it in these terms (6to4 anything).
All it is is an HTTP proxy; it receives one HTTP request from a client,
then open a new connection itself to a web server and sends the same
request, then sends the reply back. Whether the client connection comes
via IPv6 has no impact on the backend connection, and vice versa.
Here's a diagram:
request
client ------------> proxy
IPv6
request
proxy -----------> backend
IPv4

proxy <----------- backend
