Nods to 'True Grit'? (spoilers)

The original 'True Grit' is one of my favourite movies, so I know it's script pretty well. I couldn't help noticing a couple of things in Hateful 8 that seemed to be like subtle tributes.

One is that there is a character called Mexican Bob, who is a henchman of the main villain and who dies in a shoot-out. That could be a coincidence, I guess. But the main one is more striking...

There's a scene near the end of True Grit where LaBeouf (played by Glen Campbell) has been left for dead, and Rooster (John Wayne) who is struggling to save Mattie (Kim Darby) on his own, mutters something like 'Curse that Texican; the only time you need him he's dead!" At this moment LaBeouf appears, bloodied and fatally injured but ready to help, and he says "I ain't dead yet you bush-whacker." Then he helps save them, and then dies.*

In Hateful 8, near the end, after Mannix has refused the 'deal' with the gang, he suddenly collapses. The Bounty Hunter (Jackson) desperately shouts at him to wake him up, and then curses him for being dead. Then Mannix suddenly revives and shoots the Jennifer Jason Leigh character. And he says 'I ain't dead yet you....' Admittedly his language is a little stronger then 'bush-whacker,' but the line and the context are still very similar to the moment in TG.

I wonder if Mr Tarantino was paying a small tribute to the greatest Western of them all?

(* I'm not sure if the line is in the Coen Bros re-make of True Grit, but if it is it will have been spoken by Matt Damon, who played LaBeouf in that version).
