Remember that a static local variable is initialized
(either to the value specified in the declaration or to
the default of 0) at link time, which means that it is
given its initial value when the program is loaded into
memory and begins execution.  If the function includes
an additional assignment to the variable, as above, that
statement is executed EVERY time that the function is
called, which defeats the purpose of persistent storage.
