Does IE8 Really Pass Acid2? [Updated]

thevirtualcat found some inconsistencies in IE8's Acid2 results that made him wonder what's going on. Can anyone replicate these results or, better yet, explain them?
Update: 03/22 23:54 GMT by KD : Several readers pointed out this has to do with cross-site scripting prevention, as described here.

M$ has gone it's own way so long that the quickest route for them to a standards compliant browser is to download Firefox.

Another way would be to update iTunes....

Did anyone else find it intriguing that a day or two Microsoft announces that they passed Acid2 with IE8, The Web Standard Project announces Acid3 which IE8 epically fails?

It's like this- The Web Standards Project is like a kindly teacher, who waited patiently for the slowest kid in the class to understand the current lesson, before moving on to the next one.

The reason.

IEBlog article:

To maintain compatibility and be secure by default we didn't want to invoke fallback either, as original web authors might not have intended this behavior. As we all know, developers (developers, developers, developers) NEVER intend for a fallback resource to be utilized when primary resources fail. Microsoft has once again taken the initiative to embrace the developer community as a loving parent and save us from our own incompetent, foolish selves.

E8 has moved dramatically forward, and its a great thing to see. The biggest issue with IE8 which I am surprised no one has mentioned, is the performance. My PC (AMD XP1600+, ATI x700 and 1.4gb of ram), STRUGGLES Err... and STRUGGLING is a dramatic improvement? Damn, no wonder watching youtube is like watching paint dry. Who'da thunkit?
