Reverse Action Play ???

Can anyone explain how this works ??

Thanks

Reverse bets are simply "if bets" that work in both directions. This can be a combination of 2-4 Teams. All reverse bets are double action: the remaining bets in the sequence will be placed if the preceding bet is a win, a "push," or is cancelled for any reason. An "if bet" (double action) follows the sequence "if Team 1 wins, ties or cancels then Team 2." Placing a reverse bet will include that sequence and its opposite: "if Team 1 wins, ties or cancels then Team 2" AND "if Team 2 wins, ties or cancels then Team 1." As you can see, reverse bets contain two "if bet" sequences, and you must lay down an equal amount for each one: an if bet for $110 is $220 as a reverse bet.
Example:
A+B Side B+A Side
Denver -7 Miami +6
If Win, Tie or cancel To If Win, Tie or cancel To
Miami +6 Denver –7
The advantage of playing reverse bets is that you are still able to limit your exposure to losses while expanding the possible combinations that will produce winning wagers

So i bet arz-1.5 +140 & bos -1.5+130 for $2 k pays $5400

if boston game gets cancelled does this means it will go to a single bet of $1k ??

Also if i win one and lose one i lose $1100 ??

Thanks for replying
