When fob is in range, you must press a front door handle, not any handle, to get all 4 to present. (What you posted is also the way it used to be on a previous version of software... but has changed.) The only time touching rear handles works to present all 4 handles is when the hatch is up. Also, opening the hatch by the button on the hatch or by double press on the remote, is two different effects on door handles. One way presents all four handles, the other method (fob, I think) does not cause handle presentation. When the hatch remains up and if you used the method that presented handles, the handles will eventually retract, and that is when you discover touching a rear handle works to open all 4. This is the only situation where touching the rear handles does anything to present. All other situations and they are ignored.
Isn't this fun?!
