Have you ever read the advertising or user manual for a product and wondered "did they really mean that or did someone just make a mistake"?  One I found that stood out to me was from the brochure for the Yaesu FT-8800R transceiver:

ARTS™ (AUTO-RANGE TRANSPONDER SYSTEM)

Included in the FT-8800 series is Yaesu's exclusive ARTS feature which provides a "hand-shake" with other ARTS-equipped stations during emergency work. If an "out-of-range" conditions exists with, for example, a low-power hand-held unit, ARTS will alert the FT-8800 series user so the hand-held's operator can be advised to move to a better location.

Isn't this the SAME operator that the radio cannot communicate with?

Your radio pings the other radio which pings back.
If your radio doesn't receive back a ping it's time to change your location.

I think that's how that's supposed to work.

Here is video on how it works by Vertex (Yaesu).

In addition (as described in the video) there is also ARTS II

You are missing the point.  HOW can you inform the other operator to move to a different location if you CAN'T COMMUNICATE with them?HuhHuhHuhHuh?  Looking at it from the other perspective, it may not be possible for you to move to restore contact.

Your device is suggesting YOU move.  Obviously it cannot reliably tell the other user to move, nor can it tell if you are actually able to move.

maybe it bounces the signal off Voyager I, you just didn't wait two months for the response.

I read about this feature when I bought my first Yaesu HT and in seven years I have yet to see anyone in the amateur radio community use it.  I don't understand why Yaesu felt it was necessary to include this in their radios.

Actually that seems quite useful. No more "can you hear me now?" chatter. It seems like it's for simplex only.

Never used this facility, but the statement makes perfect sense to me.
ARTS worked by a ping-pong signal between radios.
If the 8800 no longer receives a signal from a handheld, but having a much higher TX power it is highly likely that you can call the handheld and inform the user
that they are no longer in TX range to  you and if they can reposition they may be able to re-establish comms.

You can no longer hear them, but they could well still hear you. It's all down to interpretation.
