What is the difference between Hemingway's third person point of view used in "Hills Like White Elephants" and The Old Man and the Sea?

I think that the fundamental difference in the third
person style of narration in both stories is one of support for the protagonists.  It is
evident in the narration of Santiago's narrative that Hemingway is in support of the old
man, as he rages against social conventions, time, and how others see him.  The narrator
tells his tale, but there is an evident support for what Santiago endures and the
challenges he must overcome.  This affirmation is not present in the narrative style of
Jig and the American.  By contrast, Hemingway tries his best to maintain his distance in
the short story.  His voice is not as evident as he attempts to let "the moment" breathe
and evolve on its own.  His use of language is noticeably more sparse and less present,
oftentimes not even adding any thoughts after each character speaks to one another.  It
reads more like a dialogue or a stage play without instructions than anything else. 
Hemingway does this in his attempt to recreate through words a moment in time. 
Language's imprecision is something that he seeks to overcome with a noticeable absence
in narration, something in contrast to his style in narrating the Hemingway Hero
Santiago's moment of struggle and eventual perseverance.
