He means if you kill the leader in attempt #1 then on a subsequent attempt another character with a leadership would become leader, and so on. Eg traya>palp>nihilus
Personally I'm not a fan, it would create strange unwanted,situations, and how would it decide who takes over? In a bounty hunter team there could be a bunch of choices for example. If it worked like that, would it not make bh stronger than before, compared to others, not only do they have backup leaders but they'd get multiple payouts? Just seems messy so maybe best to keep as is imo.
