You can't manually change a player's name on Left 4 Dead 1/2 iirc, as it's tied to your Steam Profile, so can't help that one. As far as sm_hidename_mode 2, it will display name changes for anyone who doesn't have the specific flag. Going off of default values, anyone who doesn't have the "b" (not taking into consideration any other flags) will have their name changes hidden.
