I believe there should have been a "Warning".....along the lines of "Kids...do not do this at Home!" regards the rearwards Landing thing.
Having flown over a lot of forest and jungle in my time....I am not sure I buy off on the concept of going into the trees in such a manner as is suggested.
My one time doing that following an Engine Failure in a Hughes 500D turned out well using the technique I had been taught by another fellow.
It started off with the admonition to land in the "Shortest, softest, leafy place possible"....then discussed the technique on how to get there with zero groundspeed, nose up slightly, and maximum Rotor RPM available to cushion your entry into the Trees where the Tree Limbs are the smallest and softest possible.
