Your decision to try to pass a checkpoint or not has no direct bearing  
on whether you pass or fail the Success Criteria. The only thing that  
determines that is if you meet or fail to meet what is described in  
the Success Criteria. The only impact that not trying to meet a  
Success Criteria has is that you are less likely to have done the work  
required to pass it.

As has been mentioned several times already  techniques may or may  
not cause you to pass.

Let's take an analogy.

If the Success Criteria was "The bottom of the glass water tank must  
appear yellow when viewed from the top" then techniques to pass that  
might be "Add yellow food colouring to the water" and "Place the tank  
on a sheet of yellow paper".

If the water is very dirty, then neither technique is sufficient to  
pass - the bottom would appear black or brown either way. If you clean  
the water and place translucent yellow plastic over the top of the  
tank, then you pass without using any of the techniques.

If you want to determine if you meet Success Criteria or not then read  
the Success Criteria and test to see if you pass it. Stop focusing on  
the techniques and worry about the Success Criteria.
