Figured I'd post a quick video showing this feature at work. Something I've noticed, if I simply turn off the controller it does NOT do the backtrack. It would appear the software is smart enough to determine a power off vs an actual TX signal lost. So, for this test, I stayed inside my garage and flew the drone away so I'd lose signal faster. Watch the video for results. :) Quick and dirty video with just some text added in to explain.

For those new to this, basically the phantom 4 pro has a feature where upon signal loss, it will try to "retrace" it's steps for a short time in an effort to restore signal to TX. If unable to restore it will do a normal "failsafe" RTH. According to a DJI rep the drone will backtrack "up to 60 seconds". I'm not sure what variables are at play for how long it backtracks, but in my video you'll see the drone backtrack a ways before turning directly towards the home point and heading home.

It's backtracking but doesn't see improvement in the signals strength so triggers RTH.

It appears to retrace only the last 30 seconds of the outgoing path.
I thought it was supposed to be the last 60 seconds.
