Composition scheme

A registered dealer manufacturerd goods worth of 20lak for a year.. (turnover 30lak.by selling. Same goods to dealer) So as per composition scheme limit his turnover <50k..so he is eligible to composition scheme.. And paid gst based on that.. Next he sold the goods to 30lk to a dealer and dealer sold it to retailer for 40laks..that's dealers turnover.. Again it is <50k..so dealer is also eligible for composition scheme.. Is this is assumption is right or wrong?? Will manufacturer n dealer are eligible to opt composition scheme?
