I think you need some help with the statistics. 11% is the total of intimates killed who had a restraining order. People that fight get police calls, arrested, EMT treatments and, yes, restraining orders. Guess who gets restrained regardless of who starts the fight? The male. 99% of the time.
And, your statistics do not reveal how many of those restraining orders were provoked by mutual combat. Until you have stood in an arraignment room for a couple dozen Monday mornings, when Saturday night carnage is assessed, as I have, you will not understand that drunken and jealous women cause their share of this carnage, but, as I said before, they are not usually very good at it. Hence, when it turns fatal, women get buried, men go to prison.
