Because it is an invalid address, everybody when replying will get the
same address, e.g if you reply to github your address will be 
"Katsumi Yamaoka <notifications@github.com>", it is why github provide a
reply-to header and internally, github will send to the real address of
Le Wang.

Yes unless a "reply-to" header is provided, which is the case here.

This is an option yes, but I think that when a "reply-to" header is
provided, it should take precedence on the "to" header actually
provided, isn't it the purpose of the "reply-to" header ?

This one should not be omitted IMO.
