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

My guess would be historical.  It probably made sense when somebody copied 
some code ages ago.

Another possibility is that there is an option to bail after N seconds.  If 
you are using it to set the time during booting, you might not want to wait 
for DNS to timeout.  DNS timeouts on this system are ballpark of 30 seconds.

These are my opinions.  I hate spam.
