Add multiple criteria in a rule t o set same score for the same measure without overriding it (need or logic for criteria)

I am trying to set up a new criteria for setting health score for some of our measures. For example according to the criteria for sharing users trend measure, if the # of sharing users is 0, the score of our measure (sharing users trend) would be set to red. 
However we have one more criteria for sharing users trend to be set to red based on the threshold values based on the sharing users trend that we have provided in the rule named as 'Scorecard: SHARING USERS - RED'. Will having 2 criterias in the same scorecard rule conflict each other? I want the sharing users trend measure to be set to red in the scenario where the # of sharing users are 0, even if the sharing users trend value differs and is not necessarily confirming to the threshold values set for red score. So basically I want my 2nd(#sharing users as 0) criteria to override the old criteria(sharing users trend defined with some threshold values)
