I considered "takes Functions as arguments" and "calling the
functions" as the same thing. The documentation words it as the
"specified function is fired." It doesn't specify that the functions
have to be anonymous, in-line functions. Too bad; I would have liked
to have called external functions and not repeated code.
Calling functions and passing functions (which can be anonymous or
addressed as a variable) are completely different. Calling a function
will cause it to be fired immediately, by passing and an anonymous
function or function reference this allows jQuery to fire them at the
appropriate time. That's really the key to why they need to be
referenced functions, so that .hover() can control when they are fired.
There's nothing stopping your from calling your external function, as
the hover example showed:
http://docs.jquery.com/Events/hover#overout
What you're trying to do is avoid the extra 12 characters (or more
with spaces) per argument to the .hover() function.
