Flux talisman and cutting off hydra's heads

Hi, guys. I stumbled upon on a rather interesting question, that is, should Flux Talisman actually cut off hydra’s heads? If I read correctly, the hands of a user transform into something like whips of energy. While the original whip doesn’t cut it off, which is very confusing. Please explain if is this a supposed feature or if it’s just a bug.

Are you playing troll?
