MoM protection hit

I don't know if it's just me, but I'm confused with this protection hit. I was healing my dying teammate and the killer hit me. My teammate got the stack, but I didn't. What!? Also, I sometimes didn't get the stack when I was hit around an injured teammate.

Can anyone explain the "protection hit" here or is it a bug in ptb?
