Why is he doing this in Swedish and two versions of Filipino? He apparently speaks English, so I assume he could adapt his code to do English entries as well.
I guess he only has a finite amount of time and energy. Converting the bot might be the easiest part, but then, you also need to convince the English 'pedians.
The English wikipedia is less desperate for article counts because it's already got a huge number. Wherease the other language wikipedias are always looking for more content in their specific language. So, in essence, you could say that he'll get more issues by doing this on the English wikipedia.
Ebglish WP has more people a ailable to give him a hard time for what he's doing.
Bots sometimes have trouble on EN.Wikipedia - see for example the megabytes of discussion generated by the fair-use image bot which was following existing WP rules and helping WP follow the law.
