7th Edition Necron reanimation save 4+ after shooting with DL

Hi everyone, I hope that this is posted in the correct area.

I was playing a necron player the other day who had 4+ reanimation save, this save would have been lower due to buffs the player had on the unit, however their maximum reanimation save is 4+. This is reduced if you hit them with something that is instant death.
When I hit this unit with a DL (instant death for a necron troop) the player said that his save was reduced but it was then buffed back up to 4+ again as the unit was under cumulative reductions for reanimation.

I am wondering if this is right as it seemed unfair to me, but I can see both sides of the argument.

Your thoughts on this topic would be greatly appreciated.

Thanks in advance.

There's a topic here that covers this. Hopefully that will answer your question.
