I think Audible did a R/S coupled with a growing business plan and is doing well.

The R/S doesn not effect the value of your holdings, based on the R/S alone. It`s what happens after that matters. If there is no bullish event to attract buying then the PPS has lots of room to fall, but if it is done in conjunction with a big contract/improved business, and that R/S gets the company a nasdaq listing then it could be beneficial.
In most cases in does not benefit shareholders. The above example is an exception.
