My feeling has been that
bash parses them to make only one '/' in the command parameters. There is no difference otherwise. It's just a feature in
bash not available in other older shells like
sh, where, I hope, you'd get an error for such mis-types.
Actually, AFAIK, system calls such as open(2) ignore consecutive slashes. I don't think this has anything to do with shells, and I wouldn't expect a shell to modify or complain about consecutive slashes.
