Good Question.
The oil analysis instruments detects the TOTAL number of moly atoms in the mix, it would not differentiate between the original TYPE or FORM of moly.
Edit: The total moly showing up in the analysis would come from piston ring wear PLUS the moly additive, minus the moly that was "uptaken" to internal parts. A virgin oil analysis should be run on the formulated oil so when a used oil analsis is done, one can determine what is ring wear and what is moly additive.
