Because if you're just passively last hitting or you're winning trades already, you don't need another doran's. Get a Vamp Scepter for the life steal for superior sustain. You're going to turn it into a Bloodthirster later anyways.
But yeah, Get a 2nd dorans if:
...You don't have enough for your big items.
and you need the extra power in lane that instant.
