Synchronization Settings > Mirror (with use database to detect changes) Dont understand figures

Hello, i wonder in this forum can explain de coerence of icons presented in scenario:
Synchronization Settings > Mirror (with use database to detect changes)
I Dont understand figures

Create: (left figure: >+); (right figure: RB-)
Update: (left figure: >+); (right figure: >+)
Delete: (left figure: RB-); (right figure: >+)
(attached file with figure)
*RB - Recycle bin

Anybody can explain this figures?
For example for first row (create) it seems to me incoerent, because at right not to delete.


Thanks.

When you hoover your mouse over each of the six icons, you get a text-hint clarification.
E.g.
top-left: if you Create a file in the Left-side location, that left-side new item will be copied to the right
top-right: if you Create a file in the Right-side location, the new right-side item will be deleted right-side (because you are mirror-syncing left-to-right)
