Indeed. I was able to switch to every CDG-SIN flight (both midday AF182 and evening AF256) over the following four days or so. I was travelling on one of the days where the evening flight was the only one operating, meaning leaving at midday wasn't an option, meaning all the flights offered would've resulted in me arriving many, many hours after my connecting flight had left. I'd like to think a call to the PSL would've eventually fixed this had I accepted the offer, but for 150€ I had no interest in taking that risk
