Scant, that page then references the list on page 105 directly. Specifically on that list is "Inflict a consequence."
Technically, by the rules, you cannot get a free tag on your own aspects (per page 106) but this is directly contradicted through out the text.
Basically, you're right. You can't read the rules that closely. But there is no specific contradiction, so I see no reason to say that, by RAW, you can't tag your own consequences if you inflict them upon yourself.
I'm not saying it's not a good houserule though.
