You are right. I expected the other order and I didn't read the text. (There are only like only 10 words in the page, and I didn't read them :)!)
I just looked at GMail, and it uses From/To/Subject . You don't have subject!

Also the page does not understand:
"Joe Doe"<jdoe@example.com>
but I don't think it's 100% necessary, don't rush to implement it.
