When two Mordekaisers use their ultimate at the same time, they both enter the death realm. When Mordekaiser 1 dies while his passive is still active, the Mordekaiser 2 will be permanently damaged by Mordekaiser 1's passive until Mordekaiser 2 dies, giving Mordekaiser 1 a free revenge kill and possible free shutdown gold.
