why multiple statements?

I just noticed this piece of code

public function epoch() hint="returns the number of milliseconds since 1/1/1970 (local). Call .utc() first to get utc epoch" {
  /*
        It seems that we can't get CF to give us an actual UTC datetime object without using DateConvert(), which we
        can not rely on, because it depends on the system time being the local time converting from/to. Instead, we've
        devised a system of detecting the target time zone's offset and using it here (the only place it seems necessary)
        to return the expected epoch values.
*/
    return this.clone().getDateTime().getTime() - this.utc_conversion_offset;
    var adjustment = (this.utc_conversion_offset > 0) ? -1 : 1;
    return this.clone().getDateTime().getTime();
    return this.clone().getDateTime().getTime() - (this.utc_conversion_offset * adjustment);
}

Only the first return will get executed! Why the other code?
