No but it did allow him to physically turn his legs into springs. And that's all that fruit was meant to do. Luffy's is meant to turn him into rubber. Does that mean if you cut open aokiji or Crocodile their body parts will be made of ice and sand? No, but that just means they're true logias. As soon as you start slicing, the part that was cut away will just regrow back.
