Some should really read "very few".
Seymouriamorphs are classified as reptilemorphs and are not amphibians. They have amphibian like characteristics but are most certainly reptiliomorphs.
Diadectomorphs are just plain confusing and I do apologize. As of RIGHT now, they are not considered reptiles
or amphibians but rather they hang in tetrapod/amniote limbo where they have stayed for the last 8 years or so.
The over riding point behind all of this talk of ancient lizard/fish/frogs is that Duane Gish incorrectly stated that Seymoria and Diadectes are being touted as ancient transitions of Hylonomus and Paleothyri. There may be a massive debate over whether or not certain biological parts of one or the other are present in other forms, but the article you originally linked was wrong for the reasons I have been stating.
I had some link to a huge peer-reviewed taxonomy website that I know might give some insight but I can't for the life of me remember it.
