no all it is how close the share submitted matched the network difficulty. The high share is utterly worthless and is just like any other share before it that doesn't solve a block but its that it was a share that came close to the 65 billion needed. When I rented hash I got a 7B share within a few seconds but never had one greater during the hours I rented it.

With EVERY hash generated and share submitted it either solves a block (So greater than 65billion) or doesn't solve a block (lower than 65 billion)
