Well there is alwasy the "artistic value". Even western titles sometimes don't make much sense by itself, or are grammatically/orthographically incorrect. If you combine this with the fact that the Japanese often use multiple meanings, by using wordplays with non-matching Kanji and Hiragana or non-matching Kanji and Katakana in song lyrics and elsewhere, then I have to conclude that there is a high possibility that those different meanings may very well have been intentional.

And what I ment with the original post, was that the blog poster made a contradicting statement, that the author himself may have made a "disservice for the original", which doesn't make sense, IF the author himself made it. Because if he made it himself, then the subtitle is "original" as well and not some "3rd rated copy" or something like that. I simply made sure it is clearly not a translation error, but something that was either done by Isayama himself, which is the most likely, or either the magazine (Bessatsu Shonen, did I spell that right?) or his publisher (Kodansha), still for something major like a subtitle, I'd say the author had a final say in this.

Calling it a mistake is possible, but think about it... Do people today say: "Attack on Titan is such a stupid name that I would never even try to check it out"? I don't think so. People generally simply accept that name from what I see. It is an easy to remember, easy to distinguish (sub)title for a popular manga series and, by extention, anime series.
