At the end of the day that contact point has to go over the whole razor edge, which can be achieved by all kinds of strokes.
So, honing smiling blades is pretty straightforward.

Warped ones, however, have one convex side which is just like any smiling blade - not a big challenge, but the opposite side is concave and that's getting honed only on the edge of the hone.




Well, it's not really necessary, you can still rest point A on the hone (and for great edge you probably have to in order to lower the pressure at the contact point B' where the honing happens), but yes, for the average person it well may be an easier direction that they can simply follow.
That's all there is to it!
