So, if there are 3 backends (0, 1, and 2), the order will be:
1. Execute in the last backend (backend 2)
2. Wait for execution.
3. If okay, execute (paralelly) in the rest of backends (in this case in backend 0 and 1)
4. If okay, return okay to client.

or

1. Execute in the last backend (backend 1)
2. Wait for execution.
3. If okay, execute (paralelly) in the rest of backends (in this case in backend 0 and 2)
4. If okay, return okay to client.
