The two-finger scroll is not an official gesture in webOS, but rather one that has been built into applications to allow for quick-scrolling to the top or the bottom of the app. This gesture was first introduced in the twitter app Carbon by dots & lines, where they dubbed it the "Power Scroll". To activate the power scroll, put two fingers side-by-side on the screen and then just flick upwards or downwards, just as in the screenshot to the right. Since debuting in Carbon, the Power Scroll has made its way into other apps, such as Paper Mache and Internalz Pro, and even into the web browser on webOS phones thanks to sconix's Advanced System Behavior patch (available in Preware or webOS Quick Install)
