My speech continues vs my speech is continuing
When I was watching a film festival program on television, Mr. Sharuk Khan(Indian actor) was giving a speech in Bengali(local language) not fluently and in English fluently.First, he starts speaking Bengali little with difficulty then changes to English rest of the time.While speaking English.he pauses and says "My Bengali speech continues, has not stopped yet ".Saying this,he goes on speaking Bengali and English.This is the context. Now my question is Why does he use "My Bengali speech continues" in present simple tense and not "My Bengali speech is continuing" in present progressive tense.? Also, I see these types of sentences in news headlines such as "Fight over demonetisation continues in parliament" so in this case why is simple present used and why is not continuous "Fight over demonetisation is continuing in parliament" not used? Please get me correct if I make any mistakes in course of writing.
