How does tenzing norgay develop events in "the dream comes true"?

Norgay started the narration about the climb from himself but then narration is shifted to Hillary’s climb and focus is on the events of Hillary’s incomplete account. Later he resumed the narration of the adventure providing pauses and bringing in Hillary time and again. It seems like the point is being made that the climb would not have been possible with anyone’s single efforts rather it was a joint effort regardless of whose step was the first step.

the rhyme scheme is abab cdcd efef gg.
