I think he just misunderstood or not aware of this feature especially for those who are not very active in sports betting, at first glance they think this is a parlay bet whereas in parlay betting you are not allowed to take 2 options in the same match well obviously he wondered why someone would make that bet. Another reason is that a few years ago Stake removed this feature and then made it available again with a different name from BetBuilder to Same game multi so some users may be a bit confused. Previously I have posted this topic but in a different mode, I just found how to make parlay bets using this feature (BetBuilder) and I'm sure there are still many users who don't understand this one, that's why I posted it here yesterday.
