i don't see the issue with that, i remember being dropped of the skids of a jet ranger a few years ago while diving off the cost of Texas, i was happy to dive off a rib but it was suggested by the pilot that the helicopter would be faster and just as safe, i'm a portly fellow and the dive took place at the same height as the R44 in the GIF file, the helicopter did not tip over and there were no issues there, my dive partner was a skinny girl who followed me in and again there was no issue.
The pilot in the clip could see what was going on and therefore could anticipate the weight transfer and could correct it as it happened. If the guy getting off the R44 decided to go from the seat to the boat with out preparing for the transfer then i could see there being serious issues with the helicopter going in.
