All node in close range - yes.  Nodes further apart could form a 
different subnet.

Well - depends.  In a 50meter area - yes, a single ESSID is good.  It's 
the same area where a subnet can form and have a single ESSID and where 
link-local addresses are visible from each other.

That 50meter is a hard limit specified.

Yes, in some cases yes.
