Makes perfect sence
When dealing with toe (front or rear) The number you want is total toe. This determines if the car will wear the tires. If the toe is "in" or "out" it will not cause a pull unless it is waaaay out; but then it would be more of a steering problem, not necessarily a pull. You always start with the rear of a car to do a proper alignment. Generelly set camber first as this majorly effects toe settings; then finish off with the toe. (some cars you do bothe settings at the same time)
(those numbers were off the top of my head, the point being that if the total toe was at specs, the car was OK) Total toe is the tire wear issue, the factory sets it to the cars setting (most of them "0" to "20")
The 90's series Ford escorts only have one adjustment for rear toe on one side. You set "Total toe" and lived with the thrust angle being off. Unless the thrust angle is excessive you won't see or feel it in the drivability of a car; but I do perfer to set this number true for a good alighnment.
