If you have a scheduled workflow with a saved search filter, what would be the purpose of setting a saved search condition on each action that uses the same search as the filter?

That does not seem necessary. The saved search on the WF means that all records that meet the search criteria will initiate the WF. Then all actions in the workflow will be performed to all records unless you add more conditions to each action If the actions are using the same saved search as their condition then that is duplicative and providing no additional criteria or value to the WF. It seems very unessecary

Understood, thank you.
