What do you guys think?

This is quoted directly from a website and I was just wondering if there is any truth to it as it seems dangerous.

"A safer method of sexing juvenile snakes is the "popping" of the male hemipenes. The animal is held inverted in the left hand, with gentle finger pressure just forward of the cloaca. The ball of the right thumb is placed on the tail, about twenty scales behind the cloaca. The right thumb is then rolled forward toward the cloaca. This pressure on the tail will cause the hemipenes of the male snake to be everted."

Please let me know what you think.
