>Not only does it create the conflict range, I think it actually does the work of reading the data, it just isn’t returned to you. This is why it is an O(N) operation with the size of the offset. This is true. The data is never returned to the client or anything, it's just that on the server the b-tree data structures are not augmented with the necessary information to do log(n) offset seeks so they have to scan. This is an orthogonal issue to all of the conflict stuff.
