I doubt it matters where the high point of the saddle is regarding how ‘clean’ the take off point is - it would probably be the angle the saddle is sanded to, coming down from the ridge, that matters.

The main idea is if your brake angle, nut or saddle, is twenty degrees then your saddle or nut top edge should be one half of that angle, ten degrees. This way the string will make firm contact with both the leading and trailing edge of the bone and prevent the string from vibrating over the contact area.
There is more to it and I recommend reading the Frets website as there is a lot of useful information condensed within.
I do see some round the top of their saddles and wonder about that practice?
