Just to put a point on this, both Pemberton and Thompson stated in their reports that on first contact and deployment into line of battle Loring displaced to the rear and according to Pemberton was, "thrown back so as to cover the military road," while Thompson reported Loring "fell back then a half mile, and formed in the rear of the entrance of the military road with the Raymond Road."
Clearly indicating they knew the location of the military road. Which was the subject of the 05/14 order.
More subjective but still noteworthy, in his report Pemberton stated that he, "did not issue orders to continue the movement at an early hour the following morning." The point being, if he didn't issue any orders during the night then "the movement" in the original 05/14 order was in place.
I have seen nothing that indicates the intent of Pemberton's order was to move east to the Turkey Creek Road when they clearly knew where the Military road was. I believe it's the common assumption that Loring moving to Ellison's must mean the route intended was the Turkey Creek road. And it is plausible based solely on the change made by Capt Lockett, whether in error or by some territorial anomaly requiring a change in the route. But its just as plausible that Loring was moved in advance to block the Edwards-Raymond road, while Bowen and Stevenson passed behind down the Military road.
