I thought it was as antisieze but in other procedures in the same area they specify an antisieze compound. So, I'm confused (again). ;)

I work on large, powerful GE turbines every day. Yes, it is an anitseize trick. Milk of Magnesia dries to a fine powder. This powder will not deteriorate with heat. Normal antiseize will deteriorate and dissapear with time during extreme heat cycles. M.O.M. will leave an even coat that works like nothing else.
