Nova sabotage drone drops recources

In StarCraft 2 Co-Op it is possible to obtain recources via Novas Sabotage Drone ability. If the teammate is the Commander Han and Horner their passive ability allowing units to drop a percentage of their price in collectabe pickups upon death extends to the Sabotage Drone spawned by Nova. This unit/ability only costs energy but upon detonation it also drops a pickup containing 7 Minerals and 2 Gas. I did multiple tests and it seems to be affected regulary by mastery (double salvage chance) and is present in both the Tactical Dispatcher and the Infiltration Specialist prestige which seems to suggest that this is always the case, however I have not confirmed this. This behavior is completly unaffected by what/if the sabotage drone kills or if allies are nearby.
