Probably, because Asians are positively stereotyped as being good at STEM. But a stereotype is still a stereotype.
IT has, for example, become the easiest way to get to the US on an H1B visa. As a result, Asia saw a boom in IT education, has many qualified instructors coming back from the US etc. It also helps that IT is probably the highest-paying profession where language skills are somewhat secondary.
I'd also add that your response was far more nuanced than the poster I was originally responding to, which is why I was asking for clarification in the first place.
