The "suicide" strategy is much harder to pull off effectively. The team to go to that strategy would need to "win" by more than five goals. If the other team can score only enough to keep the difference less than five, then they win by the regular rules. This would mean that a team attempting the "suicide" strategy from the outset would need to be much better in that paradigm than the other team. If we assume that the skills involved are similar, this would mean that they could probably win anyway using the normal rules. Adopting the strategy partway through the game -- say, when behind by three goals -- could be effective, but if the other team knows about this, they would keep the difference to only two goals. It would result in either a heavy emphasis on defense, or a strategy of scoring one goal and then passing the ball around for the rest of the game.
