It shows that Richard Allen and the girls, according to the timeline, were on the South side of the creek when the white van drove nearby. This explains the movement of the girls between abduction and murders.
It's true, at the time that the phone stopped moving, Richard Allen and the girls had moved farther away from the road. The may not have been visible from the road after they relocated to the ravine.
"A chart in Cecil’s report outlined the recorded movement for Libby’s phone on February 13, 2017:
1:31 pm – 2:08 pm – 1,682 steps (707.34 meters)
2:08 pm – 2:18 pm – 414.38 meters
2:25 pm – 2:32 pm – 66 steps (50.64 meters)
2:31 pm – two-floor elevation change
Cecil’s testimony explained the iPhone uses 10 feet as it’s estimation for distance for a “floor,” meaning the two-floor elevation change would be about 20 feet. The Health App, he explained, doesn’t record a duration for the elevation change. He said that it happened during the steps taken from 2:25 pm to 2:32 pm.
“February 13, 2017 at 2:32:39 pm was the last date and time the iPhone logged movement until it was charged and forensically examined on February 15, 2017,” the report read."
The second map shows location of girls, van, and timeline.
