What actually changes is the type of the SRC object and default object (I).
So if you call a function from an item, the SRC object and the default object (I) references an item type, if you call from a character the SRC and default references to a character type .

The type means what default proprerties/function (like STR for a character) can be accessed from both SRC and the default object (I).
In your case the LIST command is a "global" command and can be used in a function that is called by items,characters and server object.

I am also sure that when calling a function from the server object, both SRC and default object are set to the server object only when the function is launched from the console.

Example:
[FUNCTION test]
log <name> <src.name>
serv.log <name> <src.name>

If this function is launched from the console the results will be:
1st line) Myshardname Myshardname
2nd line) Myshardname Myshardname

If this function is launched in game by typing .test the results will be:
1st line) An error, because log isn't accessible by a character type
2nd line) Myshardname, Charactername

If this function is launched in game by typing .serv.test the results will be:
1st line) Myshardname, CharacterName
2nd line) Myshardname, CharacterName

Even if you typed .serv.test the source object that called the function is still a character.
