Earlier quoted context omitted.
>1.) Xiaomi worth billions of dollars, not 1.4 trillion, but way more than most companies. They're referring to Alphabet's (Google) market cap, not Xiaomi's.
Pretty clear that GP understands this, since his next point specifically addresses Google. I think he's saying that Xiaomi is also a big company, albeit less big. Seems like a fair point.
The GP responded to each line in the original comment with a number. So, their point about Google (point #2) was seemingly unrelated to their point about Xiaomi's market cap (point #1) as they addressed different parts of the original comment.
The GP mentioned Google perhaps not because of the market cap mentioned in point #1, but rather as a response to the original comment's mention of American companies.
This is further evidenced by their use of point #3 to refer to the term oligarch, which was the third topic raised in the original comment.
You can see how not clear this is based on other replies to the comment as well.
