What’s the difference buying now and the first purchase? The price isn’t going up much.

It's just hedge against the uncertain regulatory environment.
One does not know tomorrow China govt comes up with what. If you buy everything all at one go next day some heavy handed regulation comes jn stock plunge....

It is not necessary and in long run does not matter that much but in a very uncertain volatile period splitting a purchase reduces volatility in your portforlio ....in case of bad news you still have some bullet for entry.

If you are sure worst is over just take a big bite.

Alibaba will move up ...I am quite confident ....
