This is a really tough question to answer. There are several things in play here. You have the theoretical ideals of how to write things, which is what the first column focuses on (and most of the book for that matter). Then you have how people have taken different symbols to seem more like it is in real life. The problem with the latter is that different people see different things as real life.
The members of the DAC (historically and now) made certain choices as how to write. When taking a close look at what they chose to do, it was discovered that they chose to make hand shapes with angled fingers rotated downward for when the fingers were angled down (like you see on this page you sent), and rotated up when the fingers were angled up (which would be for the white palm facings). So this listing isn't extensive because we don't know if there are other speculations that have not been noticed yet. But besides that, we didn't want to tell people that the theoretical ideals presented in the book aren't always 100% used.
An example of that is the Stefan. My understanding of how he writes is that this page would look completely different. In fact, he mentioned that the second row confuses him because the thumb does not match where the thumb is in the real life picture. That is true. This is an exception of the "real life" matching that is built into the ISWA as the DAC members use it. Because of the angled fingers in the hand shape, placing the thumb on that side would mean that the thumb is also angled forward. It was decided that since the hand symbol with the white palm facing and half-black half-white palm facing place the thumb on that side, the same thing would happen for the black palm facing even though it is not like that in real life.
So I realize that this was a long winded answer that doesn't really answer your question other than "yes and then some with several exceptions". Since I know that you are trying to make it so that you can search for various possible writing that are truly the same thing, you'd have to also take into consideration that there are people who have great differences in how they would write the same thing to the point that they wouldn't be able to readily read the other writing without some switching of philosophical writing hats, if you will. :-)
