I think that has to do with the thickness of the bones. The article discusses that a bit too. I'm sure it's just like a lot of other types of calls, it all depends on the preference of the user.
I used to hunt geese every day of the season and took a lot of folks with me when I went. I tried a number of different goose calls but finally settled on those made by Tim Grounds. Tim's calls were/are preferred by almost every goose hunter in this part of the world. When I'd ask a hunter why he was using one of those calls, he'd usually say something like, "Because that's what everyone else is using."
We tend to use calls that sound like those that others use. Sometimes, that's a mistake when hunting turkeys. At times I've only been able to call in a big gobbler by using a really different call. Not many people use wing bone calls, at least that's been my observation. I know people collect them but I've never seen one in the field.
It might be really interesting to make one and use it to see just how well it works. I may have to look to see if I still have a wing around that I can "process".
If you try it, please let me know how it comes out.
