Basically, what happens is that I assume they cannot see any of the images and a large portion of the header has collapsed and all of the content (including some ads - hence the PLU connection) moved up into the ATF.
Actually this isn't a likely case of Google getting it wrong, it's a sign that your code may be improperly nested and/or rendering in quirks mode. I've seen this with several wordpress themes lately where the header and body of the code don't mesh correctly. It LOOKS fine to me in FF, IE, etc but when rendered by Google preview all the content gets shoved onto one line.
Solution: Visit the markup validation section of W3.org (http://validator.w3.org/) and try to resolve as many of the issues as you can. Pay particular attention to the code in the header.php file (if wordpress) and the start of the rest of the page. I've done this before and it resolved the problem.
