I was always told by my mot tester that the reason you shouldn't mix 5.1 is because it is silicone based and most systems, unless designed for it, can deteriorate seals and pump internals. It can also cause issues with different boiling temperatures if mixed.
I've never heard a problem with doing a complete flush with 5.1 but personally, I wouldn't want to.
