h.each_with_index do |(k,v),i|
   # ...
end

the short answer is: because. The longer answer is that when you  
don't do _with_index you're still lumping them in (use one arg to  
see) but you're getting splatted implicitly so your two args get  
values. When you use _with_index you're getting an array of the pair  
and the index.
