Clearly the pilot in the video has some good general handling skills, but in regard to the rearward touchdown, if you ask the 2 basic questions;
1. Do I need to do this?
2. If yes, could it kill me?
...they might come up a bit short on the "thinking it all the way through" category. Any time you are travelling close to the ground in a skid equipped aircraft and the skids are not parallel to the direction of travel - and in this case, pointing in the direction of travel - you have increased your risk of an unexpected outcome. Accurate flying and good handling aren't the whole story.
