Not necessarily. Spokes stretch so if you do it all the way down then when it stretches there is no thread to tighten them up again.
I didn't say all the way down, I meant the top of the nipple covers the thread, which ensures an even starting point - there is still loads more thread/nipple room to tighten it up.
