GarthB-- You have quoted the old rule, not the new rule. I did helpfully point out that the rule has changed, and that fact may alter interpretation, but you don't seem to have read for comprehension.
And of course a line is between two points. I think the new rule specifies the two points they have in mind, and in this situation (as opposed to a runner between his occupied and advance base, in which case there are generally two baselines defined by 3 points) one of the two points is the runner himself.

You are right, I forgot that my on disc rule book does not reflect the change in language, HOWEVER, the rule still describes the runner's deviation as "three feet away from his baseline". The baseline runs through the points, if not, any runner in a rundown would be out by your interpretation.
