No, separate counter for each element. Definition could look like:

table x {
    chain y {
        ...
        set s {
            type ipv4_addr . type ipv4_addr; flags counter;
        }

        map m {
            type inet_service : ipv4_addr; flags counter;
        }
    }
}

Listing could look like (similar to listing of timeout flag):

table x y {
        set s {
                type ipv4_addr
                elements = { 192.168.100.1 counter 5, 192.168.100.2 counter 0 }
        }
}
