CMTS/Public Wifi provisioning question

I expect Frank Bulk to have an opinion on this, all others welcome.

Hat tip to Bright House -- I've noticed lately that I don't have to go
through their captive portal when using their public wifi hotspots (they
participate in the CableWifi consortium, using WAPs built into their
6580 and other cablemodems, and offer a carrier-specific connection SSID
as well).

This has led me to a point of curiosity:

If I'm the subscriber, and I've paid for 15 mb/s down, then my wired
connection and my private wireless (if provisioned, and they charge
$10/mo, so I'll do that myself, thanks) are using one ... DOCSIS path? 
back to the CMTS.

I assume that cableco provided voice is on a separate path, and I'm sure
the TV service is -- if it's even IP at all.

But the question is: is that public wifi service *also* on a separate
bandwidth-limited channel out of the cablemodem?

Offline replies fine, unless you think it's of sufficiently general 
interest; I expect it's implementation dependent.

Cheers,
