IE8 Support ends before Server 2003 R2 support, how is this possible?

I have just been shown a warning that IE8 is out of support and vulnerable, yet Server 2003 R2 is supposed to be under support until 2015.  If IE8 is the latest browser that can be installed on 2003 R2 (and require by OS functions eg. updating) then surely this invalidates security of the whole OS.

So which is it? Is Server 2003 R2 secure and supported to 2015 inc IE8 or isn't it?
