This is not the rule. It is misunderstood and it has got to a point that it is even wrongly taught that way because it is easier to understand.Like with the naked eye the 'unwritten rule' of benefit to the attacker
The rule is "You make the decision which is likely to be least erroneous". In the vast majority of cases the attackers benefit from this rule as the attacker runs twards the goal line and defenders away from it or stationary, and the flashlag effect dictates if you think it's just offside or very close, it infact is onside. But the direction of movement is not always as described here.
