Does it help negate the shutter shock problem?

Good question before I joined this forum I didn't know there was such a thing as shutter shock. Ignorence is bliss. I don't think it would stop SS. It lets the movement of the camera body subside that's caused by pressing the shutter button. So it should help in general but probably not for SS.

The 1/8 anti-shock delay causes a delay between when the shutter closes and before it runs for the exposure. The initial shutter closure is really violent and the shutter can be seen bouncing quite a bit, so the 1/8 delay helps wait for that initial shock to settle a bit before the exposure begins.

I made a 1,000 fps animated gif slowed down somewhat from the video to see the shutter action a bit better, E-PL5 is shown at http://i100.photobucket.com/albums/m36/photoguy340/dprstuff/epl5shutter2_zps60fc6f28.gif

As for the "anti-shock delay", the clue is in the name that Olympus chose for that menu item, and in fact should really be named "anti-shutter-shock delay (hopefully)".

page 74 of the E-PM2 under Anti Shock

"Choose the delay between the shutter button being pressed and the shutter being released. This diminishes camera shake caused by vibrations. This feature is useful in situations such as microscope photography and astrophotography. It is also useful for sequential shooting (P. 35) and self timer photography (P. 35)"

The manual is not sufficiently precise here. The regular anti-shock setting (but not 0-second AS) introduces a delay between the first phase of shutter action (the shutter closing to end live view and prepare the sensor for exposure) and subsequent phases. You can easily tell by the fact that the EVF/LCD goes black immediately after you press the shutter button (since the shutter is closed).

Ordinary self-release, by contrast, introduces a delay between the moment you press the shutter button and any shutter action, including the first phase. Consequently, on a camera not capable of 0-second AS (electronic first curtain), I would usually use anti-shock with suitable delay rather than self-release whenever I want a delay before the shutter opens (to eliminate blur due to button pressing and/or shoot a selfie).

Its only a delay set to let the motion if any imparted to the camera body subside before the camera operates the shutter.It doesn't change the shutter operation.
