It won't overlap with the one you are using for yourself on the same device.
DOCSIS has service flows with different priorities. I don't know if they are allocating specific channels for it or if it's just a different service flow, but either way it is a lower priority and should not cause contention with regular user traffic.
Really it is just the power they seem to be complaining about.

IIRC there are only three non-overlapping channels on 802.11g and six on
802.11n; I can see more networks than that from my basement.
I haven't been keeping up with the technology, but in the ancient of days
wasn't the uplink side of DOCSIS also a limited-bandwidth, shared resource?
