"Any idea where the video was taken?"
I tried to resist, really I did, I was hoping somebody else would say it.
Videod from the back of a boat I am almost certain
Sorry......
Maybe one day I will grow up, but in the mean time, jokes aside, I know exactly what you mean....

Advancing TR blade hitting the water
you can see a bit of bounce back on the tail.
if it would have been retreating blade touching first
would it have swallowed the tail more and sink him in.
he was in the light flare the pitch might have been that high.

Just bend the "incident" tabs back straight so maintenance doesn't see it.
Nothing to see here.
I wonder if a tail rotor strike inspection was carried out?
Or the next poor sod to fly it sometime in the future will find out the hard way?

Plus having the TR driveshaft inspected as that will have been shockloaded to some degree!

Given the three orders of magnitude on the density of water over air I am amazed the machine did not kick more in the yaw. TR RPM/pitch didn't change instantaneously and the fastest part immersed .... blah blah blah.
The only way to absorb that energy instantaneously, as Crab suggests, is to wind up that TR drive shaft ...
But, being a nerd, I reckon the entrained flow and low pressures would have caused cavitation limiting the lift of the affected tips. For the short durations of impact anyway.
And, as Agile says, if that TR had been going the other way the effect may have (paradoxically) been much worse.
Notwithstanding the noted implications of an abrupt impact of an axisymmetric planar lifting assembly inclusive of a plurality of blades perpendicularly disposed to, and impinging upon, the free surface boundary between atmospheric and a hydrostatic body including, but not limited to, H2O the conclusion is as previously determined by Sikorsky (1939) et seq ....

Cavitation is a good point, there are video of similar situation (including fenestron) often it looks like the flow of air already present is not letting water fully attack the blades, at least for a partial hit.
What comes out the event is a lot of mist; that would explain the absence of impact on the stability of the helicopter as the blade are turning (for that short time) in much less dense mix of water and air.
Lastly the aircraft structure hanging below is much lighter that water and would want to bounce back as a float would.
that does not count for the video bellow where the Fenestron got it all

This sad event (for us professional pilots) in this video that went viral took place in Brasil, city of São Luis. The lunatic who was flying the machine is actually the owner as well. Some rich business man linked to politicians.... Dont need to go any further.
This is not the first and surely wont be the last jacka$$, I truly hope the authoryties get rid of his private pilots license.

I am going to raise a lot of fire by saying so ...
yes it was not smart
yes it could/should have ended in a major fail
yes it is unfortunate that it was filmed (as it make the industry-profession look bad)
however I am sure that most of us as pilot have made bad judgment in flying once in your career, you got away with it, it was not filmed, you keep it in the back of your mind under the heading "never do again".
is that not true? it doesn't`t mean your end should come soon
