George's marriage to Sophia Dorothea was dissolved, not on the grounds that either of them had committed adultery, but on the grounds that Sophia Dorothea had abandoned her husband.
Well, Sophia Dorothea of Celle was never crowned queen and they separated in 1694, long before he ascended the throne and became king (in 1714), so there's no reason why she should count...
you can make the same argument for Caroline of Brunswick, she was never crowned Queen either and spent most of her marriage separated, yet she's listed here.

I know this reply is somewhat late, but I don't think Philip II was included since he was made a "King of England and Ireland 'jure uxoris'". That basically means he held the office of "King" through his wife, so while she actually did the ruling, he technically wasn't just a consort...

It is in the order of marriage, just down to up :) Catherine of Aragon, Anne Boleyn, Jane Seymour, Anne of Cleves, Catherine Howard then Catherine Parr.
