As you saw, `symbol-function' gives you the current definition of a function.
However, in your example use of it you can see that it is not very useful if the
definition is byte-compiled.  If you do not have access to the source code, and
if the current definition does not come from the source code but from
byte-compiled code, then what do you expect to see?

If you do have access to the source code and if the function is defined in Lisp,
then `symbol-function' will show you that Lisp code (assuming you have evaluated
the source code).
