It's a little tricky to interpret without the broader context of the first person novel it's excerpted from.
This novel is a first person narrative from the perspective of a (partly) reliable narrator (the white male protagonist of the novel - see the opening section of the quote).
You're right that the subsequent narrative (that follows from this opening section) is told in third-person omniscient perspective, but it's still nested in the protagonist's own re-telling of Jason's personal account of his life story - Jason being the Asian character. The implication being that some of the antagonistic racial framing has been interpolated by the protagonist/narrator.
How exactly is that excerpt told through a white male perspective though? It’s in a third-person omniscient perspective.
