Since this will never be noticed we can chat
You are supposed to know what foot he uses so you know if its weaker or not. When its says "move to his left foot" is doesn't say weaker side (or not) either. Additionally the variety of comments you get depends on whether you play on phone or PC because either device gives different comments for the same events in the same match. And it also says that Either footed players have 'weaker' foot.
