DNS Connection for Non-exits

Hi. When the ORPort is set Tor makes connections to the system's resolvers:
atagar@fenrir:~$ netstat -np | grep "ESTABLISHED 3776/tor"
tcp 0 0 ESTABLISHED 3776/tor
udp 0 0 ESTABLISHED 3776/tor

My understanding is that this is to provide dns resolution for exit traffic we're handling. However, these connections are made for both exiting and non-exiting relays alike. Functionally this isn't an issue, but is probably a little confusing for operators.

Am I misunderstanding the purpose for these connections? Do they serve a purpose for non-exits? I thought it was appropriate to label them as belonging to exit traffic in arm but I'll need to rethink this, lest we get some very confused non-exit operators. ;)

Cheers! -Damian
