Not wanting to get involved in any speculation about the reasons but that is also what came to my mind. Was a bit surprised by numerous statements concluding from the shape of the airframe that it was a rather benign 'arrival'.
The EC135 has quite some massive roll-over frames built into the primary structure. To bend it in a way like you see in the pictures will surely take significant impact force. Never ever was that a soft landing followed by a slow breaking through the Roof.
