Even when using 3-man mechanics, I'll do it with R3 and a left-handed batter up -- so as not to have my view of a possible check swing blocked by the runner.

Is that the rationale for straddling the line as opposed to being completely in foul territory?

Just a comfort thing.. As with any new (or perceived new) mechanic, try it out and see if it makes you more comfortable in your own position and view. As stated in another post, I too heard it was a result of getting a better look at check swings with a runner on third.....
