if the distance of the content element from the top of the page is > 0 the reload is triggered also when the scrollTop != 0 

this happens because at line 81, the scrollTop of the body is used:

```
        pan.startingPositionY = dcoument.body.scrollTop;
```

 instead of the contentEL.
So to fix this replace line 81 with 

```
        pan.startingPositionY = options.contentEl.scrollTop;
```
