Yeah; I've seen this done elsewhere and facepalmed.
Actually, I've seen this done -worse- elsewhere, where they were actually encrypting the password, using a symmetric key. So if you sniffed the traffic and never loaded the website, I guess, you'd not know the actual password...but you wouldn't need it; it as as good as for the purposes of logging in. If you did load the website, you could still determine what the plaintext password was.
It was really irritating, since I had to figure out what the encryption scheme of a backend app was doing (when I only had access to the frontend code, and the datastore).
