Ah thanks for fixing that So much shorter! (I was lazy when I removed the navigation parameters from the coding and just copied from the original, forgetting to remove the <?php?> bits. Bad move on my part xD)
I keep that home link there so that it is always at the beginning of any breadcrumb trail. It's just for consistency's take (since that breadcrumb structure (at least for my site) stays the same for all pages). Plus there can still be reasons to click on that home link (such as being directed to the second page of news which is still on the 'index', but not having a back button - an extra home button makes the link very easy to see).
