Yes, he is, actually.
Nope. That was a possible plot twist in an early version of the script but never made it into the final cut. Something similar happened in the novel too, but even then Deckard wasn't ACTUALLY an android, he just (briefly) thought he was.
They dropped it from the final script because it would be too complicated to setup that kind of plot twist and make it believable (it was hard enough to swallow in the novel even when it was just an android mind game).
Directors generally don't employ subtlety except for easter eggs and in-jokes. Don't confuse plot twists with fridge logic; plot twists aren't meant to be hidden.
