Actually, this rule was brought in by FIFA as a direct result of - or, to be more precide, as a direct consequence of - the now notorious match between what was then West Germany and Austria during the World Cup in 1982, when, given that they both knew (because the other relevant matches had been played earlier) what they needed to do in order for both teams to advance to the knock out stages at the expense of Algeria, they deliberately chose to play a most cynical game (the stats in the second half were extraordinary, comprising astonishing and inexplicable stuff such as completed pass rates in excess of 98%, - normally, this only happens when outstanding players play, and then, rarely - but no shots on target and hardly any tackles) which achieved the desired result (both teams advanced, and Algeria - who had played attractive football - were brutally and cynically eliminated).
