Double drops only from going directly to node?

Found this out early today with double drops. May be my luck, but found it odd.

Going through Krrsantan's gear to sim for his mk12 amateur salvage got me the picture thay doesn't say bonus, but when i went through ships-->fleet battles-->2e and hit multi Sim i got the Pic that said bonus.

Side note I sim'd it 5 times through Krrsantans gear and it never said bonus, and I multi simed it 3 times from the fleet battles and it said bonus for the two times I got that peice.
