What mismatch? Line 345 is the last line of this routine:

    def org(self, addr) :
        """sets the origin for defining subsequent consecutive memory contents."""
        self.curpsect.setorigin(self.follow(addr))
        self.lastaddr = self.curpsect.origin
        return self # for convenient chaining of calls
    #end org
