onPageScrolled returns zeros when scrolling between first and last item #4

LoopViewPager.onPageScrolled(...) has some logic whereby if the user scrolls left from the first item (i.e. looping across the first-last item boundary), then onPageScrolled returns zeros.

if (realPosition != mAdapter.getRealCount() - 1) {
    mOuterPageChangeListener.onPageScrolled(realPosition,
            positionOffset, positionOffsetPixels);
} else {
    if (positionOffset > .5) {
        mOuterPageChangeListener.onPageScrolled(0, 0, 0);
    } else {
        mOuterPageChangeListener.onPageScrolled(realPosition,
                0, 0);
    }
}

In my case I am scaling items depending on scroll position, but the problem would occur when anyone wants to use the onPageScrolled values. Basically whatever code logic the developer implements in his own onPageScrolled, this logic will fail when scroll transitions between first and last item in the list.

I have fixed this by having LoopViewPager.onPageScrolled always calling

mOuterPageChangeListener.onPageScrolled(realPosition,
                            positionOffset, positionOffsetPixels);

(i.e. removing the "if"-logic).

Is there are reason for the "if"-logic? Seems better to me to always return scroll values here.
