I'm going to kill the poetry by trying to explain it, but try translating each phrase like this: When you read:
"Steve Jobs did not [do X], he [did Y]."
read it as:
"It's not so much that Steve Jobs did [legendary thing X], as that he did [apparently simple thing Y, and did you notice that by doing so he just happened to accomplish X as a side effect?]"
The author agrees with you.
(Note, by the way, that my rephrasing is absolutely bloated with weasel words that diminish its impact. That's why the original author wrote the way he did, at the expense of losing the literalists in the audience.)
