Drawing a blade diagonally along a hone (to cover the whole blade) makes diagonally oriented teeth, right?

If so, then I'm wondering how much that angle needs to be preserved, in two cases:

1) on one hone
Seems like if you really wanted to ensure that the whole blade was being sharpened evenly, you'd do the standard diagonal stroke half the time, then switch, i.e. alternating between sliding in the direction of the heel and sliding in the direction of the toe. However, this doesn't seem conducive to forming teeth at all. Is it important to maintain the same angle and really groove those teeth?
2) from one hone to the next
Due to varying widths and lengths of different hones, it seems like the angles on those diagonal strokes would also be different. Indeed, I'm sure I've seen pics taken with a microscope that showed each successive set of smaller teeth oriented at different angles. Is this good, bad, or a non-issue?
