So if Woz had given $10,001, then he would have had to file it, and then when he died, it would have added $10,001 towards his total lifetime gift tax exclusion from his estate (currently $13M). But if he gave $10k (or whatever yearly reporting maximum) per year until he dies, then all of that does not get counted towards the $13M lifetime gift tax exclusion, so in a way, it is an additional tax reduction when the estate gets passed down.
