They are probably different mixes made from a recording with even more channels.

The original recordings were made with 5.1 format and later the extra 4 height channel layer added for 9.1 format. But why 4.0? I must have gotten it from the testbench in 2014 or 2015. 

 

In the booklet, I don't see microphones for height information. Most likely the were added later in mixing. Artificial height sound?

Look at this photo from the 2L website:

 

You can see 9 microphones on a pole in front of the conductor.
