This is exactly how an adhoc 802.11 network (IBSS) is supposed to work
as specified in IEEE 802.11 standard. A card can create an IBSS and
start sending beacons about it. The other nodes can join it and they
obviously need to change to the same channel. They will thus end up into
the channel configured for the node that created the IBSS.

Earlier test modes (adhoc demo mode, pseudo adhoc mode, or whatever they
are called) do not use authentication or association. Thus, they require
(or in some cases this would be 'allow') manually configured channels.
