howl of the monkey gods | The path behind the door

Hey there!
Please, take a look at this
screenshot, is there anyone know how to get behind this door?
Looks like there is a path behind this door.

There is another door like it on the right-hand path (down the rope) to the wind mechanism. Both have controls on each side, maybe for co-op?

We can see the same door and the same path behind that door in single player too.
I hope it's more than just a co-op thing.

I tried every stupid thing I could think of to get to that area from the other side in single player. There's also another path to the right at the beginning I didn't notice before. Found this video which shows co-op play:

So the conclusion is that door made for co-op. Right? Sadly.
I would love to get there as solo player. Thanks for your efforts.
