I agree -- "victory lap" is just a figure of speech. Yesterday's results were probably far outsized impact on their own, and today's are (apologies for another figure of speech) "icing on the cake".

I would imagine that they've been feeding these booby-trapped devices to the supply chain for at least a few months and showing that multiple devices are potentially bombs is just an even more powerful psychological victory. What devices can they even trust now? Will they need to go back to sneakernet?
