It may be the same case as with Stalker. A kill on each boss gives you a Stalker deathmark - I'm more than sure since I got Stalker in 2 consecutive missions - both time he was after me - and each time he came at me for a different boss. Perhaps it's a feature to let you increase your chance of an encounter
