I believe this is correct. The orders, while referencing Title 13 of the California Code of Regulations, are actually specifically referring to California's plan to require automakers to reduce emissions on vehicles starting with the 2009 models. This has no effect on older models.
Now, whether this necessitates annual emissions testing is contingent on whether Florida seeks to regulate these new vehicles for the duration of their use. If this is this case, and to remain in accordance with the spirit of the new plan, it is likely that cars predating '09 will also be tested. I imagine classic cars will be exempt, as they are in California.
However, from what I've read (the three executive orders, Title 13 of the CCR, and myriad articles on the topic), it seems as if Florida has no interest in implementing California's vehicle emissions standards whole hog. So, I don't think we'll have to bother with annual tests. But, I may have missed something, or there may not be enough information available.
