Double Completion Criteria for a task is not working

Hi team
I'm writing you because I enter two completion criteria for a task however they seem are not working.
Do the completion criteria I added follow a AND logic or an OR logic?
I mean, I added:
1) completion criteria for adding the Nation Identifier
2) completion criteria for adding Place of Birth

It seems an OR logic, because the pending worker enters the National Identifier and they are able to complete the task even if the biographical information hasn't been added

Thanks in advance
