C-h f defcustom

        VALUE should be a function used to initialize the
        variable.  It takes two arguments, the symbol and value
        given in the `defcustom' call.  The default is

C-h f custom-initialize-reset

   The value is either the symbol's current value
    (as obtained using the `:get' function), if any,

So, no, re-evaluating a defcustom will typically leave the variable at its
old value.

M-: (progn (defcustom sm-t 1 "hhaha") (defcustom sm-t 2 "hhaha") sm-t) RET

returns 1, not 2.  IOW, it works more like defvar than like defconst.
