Nobody seems to notice this "bug" so it probably isn't. But here's my issue:
In the demo there are some inline href links within the text (inside the #scroller div). Links at this level appear to receive 2 clicks.
Simply add a "_blank" as the target and every link will open 2 browser windows. Links OUTSIDE the #scroller work fine. For example, find the following:
<a href="http://uxebu.com/blog"> our blog</a>
And replace with:
<a href="http://uxebu.com/blog" target="_blank"> our blog</a>
If I'm "doing it wrong" it's non-obvious to me what it can be.
My guess is that this is due to the clickEvent that TouchScroll throws at touchEnd: https://github.com/davidaurelio/TouchScroll/blob/master/src/touchscroll.js#L596
