In short, it states about when zooming is activated in image playback review mode, in addition to turning the e-dial for zooming in and out, the EV compensation (+/-) button and the Green button can be pressed and continuous zooming-in or out action is possible, which could provide a quicker access and minimise the wear and tear of the e-dial.
As a side-tip of mine, no matter what Pentax DSLR model(s) you use, if you just want to zoom in larger instantaneously without turning the e-dial for cycles. There is an option of "Quick Zoom" under the "Playback Display Method" menu. Just enter a zoom ratio you prefer once you turn the e-dial for zooming during image review. That's it! :-)
