On https://voice.unifysolutions.net/knowledge-bases/8/articles/2712-operation-list-groups in the Notes section at the bottom it reads:
"It is recommended that large synchronization operations are set up as priority members, with smaller delta operations that will be affected as normal members"
Since MIM 2016 (and possibly earlier, I'm not sure) Microsoft has explicitly deprecated running two synchronisation steps in the sync engine at the same time, and executing a second synchronisation step (while another is already running) will now always fail with a error.
With that in mind, configuring an operation lists with a Full Sync as a priority member in an exclusion group, and an operation list with a Delta Sync as a normal member - as suggested - will allow UNIFYNow to attempt to execute the two sync steps concurrently, which will be result in an error in MIM.
Consequently, I suggest that the example should be updated to not recommend this configuration.
Also, as a minor point that paragraph should refer to "operation lists" rather than "operations", as groups apply to the former, not the latter.
