You are definitely correct that the RPO L88 and RPO ZL1 are different motors with more than just different cylinder blocks.

While the first design L-88 differed considerably from the ZL-1, the second design L-88 and ZL-1 were essentially the same with the only difference being the aluminum block. Open chamber heads, the bigger camshaft, the new Holley DP carb... all were part of the second design L-88 as well as the ZL-1. A few second design L-88s were built early in the 1969 model year (around November/December 1968 to get them in the hands of racers for Daytona), but the vast majority were built after the strike in mid-1969.

As far as the ZL-1 in question, I also have the 1980 Vette Vues and was immediately curious why it differed from the Corvette Fever article... I even had someone email some high resolution photos of the Daytona yellow car which he had to make sure that I wasn't seeing things.

Your question in the initial post is a good one. There are differences between the paperwork for orange car and the yellow car that should be researched.

One piece of information that would be very helpful in my personal research is if someone has in their possession or has access to an original window sticker for a Hechler Chevrolet (Virginia) delivered Corvette in the latter half of 1969. If so, I would very much like to get a photocopy of it (I'll be happy to pay for your trouble in getting it).
