Because it processes the back of each range, rather than an index. EG:
//----
import std.range, std.stdio;
void main()
{
auto a = [1];
auto b = [1, 2];
auto c = [1, 2, 3];
zip(a, b, c).back.writeln();
}
//----
This writes "Tuple!(int, int, int)(1, 2, 3)".
For "shortest", it should print "1, 1, 1".
For "longest", it should print "0, 0, 3".
For "same length", it's an error.
