Lockdown Seal on Assassin Corrupt Rescuer

[Stormseye]

I know some others have been running this setup, including myself, but it seems that the Lockdown Passive will overlap when using two Rescuers on one team. Is this intended or a bug? Meaning at the start of the turn, sometimes only one enemy will have buffs stripped and sealed despite there being two Rescuers. Do they just randomly pick 1-4 and if they stack then they stack? Seems like it should pick a non sealed target if one is already sealed. If they are intended to stack then why isn't the seal timer bumped to 4 rounds instead of staying at 2?

I am glad to see that nobody wants to discuss this cheesy, lame, bug-using (as the only real counter is broken) exploit "strategy", that seems to be not "nasty enough". Well done, community!
