The door in question is already a bi-fold door. It does serve the purpose Dave mentions though: When in the "open" position the door blocks off entry to the back bedroom and increases the available space in the bathroom--provides a sort of changing area.
Hmm looks like Thor changed it for 2016:
The older model:
Note the bathroom door between the two. Looks like in the new design you can close off both the bedroom and the living room from the bathroom (that way you don't have to kick anyone sleeping out of the bedroom to take a shower--although they would be trapped there until you're done).
I wonder if it is easy to convert between the two (if you don't like the older version perhaps you could get the dealer to convert to the newer or vice-versa).
Makes you wonder if they had too many issues with the old door mechanism, problems manufacturing it (new one looks easier to install)?
Its not like it is the first time Thor has used this arrangement; it's been available in the Siesta Sprinter 24SR for a while:
