Also by placing two bets on the same match on each team will mean that you will confirm lose one of those bets. So in order to cover the loss you have to win the other bet with a profit margin of more than 2x (which is impossible in most cases). So technically placing two bets on a same match means you will lose your money.
I haven't tried betting on the same team or the same players in one match, if this is the case then this is a positive confirmation that you know you lose a half of your money. Somehow it is also kind of securing your chances to win the bets but also admitting to lose half of it. I don't think it is covering the losses if in case because you can't make sure if the winning money can cover the losses amount. So personally I don't think so that betting on the same team on the same match is a good decision.
