To the extent that procedures are intended to accommodate human 
fallibility, it seems more likely that an inward leaning pin would 
ere towards becoming the latter  of an un simultaneous 
termination.  In such case, I could speculate that it would generate 
a different tonal response than either simultaneous termination or a 
pin-first model.  No data to support an arguable theory, only speculation.
