Two things to note from this....
Firstly it has LHO claiming to purchase his Coke before the 2nd floor encounter. This makes both the descent timing tighter but also the spotting of LHO by Baker through the door window difficult.
Secondly, it has LHO claiming to not fleeing the scene but almost the reverse. From the 2nd floor, instead of the closest route out of the back of the building, he takes the route across the 2nd floor, possible points out the phone to a journalist, then proceed to mill outside of the TSBD with Shelley.
