No Idea why the difference between the two but try adding a font size to this and I hope I noticed all of your issues:
Code:#testimonial {float:right; font-size: 12px; clear: right;

The difference between the two is that the pages that are displaying correctly are being rendered using strict mode, while the ones that are being rendered incorrectly are using quirks mode.
A possible fix for this would be to force quirks mode on all pages by changing your doctype.
A better fix would be to figure out what's causing quirks mode to be triggered. I've looked over it and I have to say I'm stumped here, though ....
