I don't really follow what you're saying here.

The article correctly points out that if you turn over the "9" card and it does have a vowel on the other side, then you've disproved the rule (which I should have realised).

[edit] To be clear - turning over "U" and "9" allow you to disprove the rule; turning over the other two cards tells you nothing about the rule at all.
