Is there some good reason for ntpdig to be doing asynchronous DNS?

Mark suggested I ask the devel list this.
C ntpdig goes to vast efforts to do asynchonous DNS lookup, and I
don't get why. It's not like ntpd - ntpdig doesn't have anything else
to do while it's waiting for replies, and being UDP datagrams the
requests themselves don't block.
Anyone have a good explanation for this? It looks like overengineering

False is the idea of utility that sacrifices a thousand real advantages for
one imaginary or trifling inconvenience; that would take fire from men because
it burns, and water because one may drown in it; that has no remedy for evils
except destruction. The laws that forbid the carrying of arms are laws of
such a nature. They disarm only those who are neither inclined nor determined
to commit crimes.
-- Cesare Beccaria, as quoted by Thomas Jefferson's Commonplace book
