Is there a reason this audio has 3 licenses? Are they functionally different?

Yes. They are each very different. Well, CC-By and GPL are very different, but there is also a reason for version 2 and version 3 to be listed on this asset. 

GPL makes it easy to use this audio in your project if your project already uses GPL content. 

CC-BY makes it easy for you to use it in your project if your project uses anything other than GPL content.
