No, I do not realize this.

Assume a counter which is not read only incremented/decremented.
Its "application specific conflict resolution" ensures
that the schedule is serializable restricted to the counter value.

Things are much more complex when the counter is read (and incremented).
Usually, serializability is lost, then.
