The thing is, "Mixed tactics" and "Doubles tactics" are different.
Standard doubles tactics assumes that both players are reasonably similar in skill. In Mixed that's often not the case, with wide disparities. If both teams are good at Mixed, their tactics will be SIGNIFICANTLY different than doubles tactics.
If one team is playing mixed according to "standard doubles tactics", then AGAINST them the correct strategy will usually be just to hit with the weaker woman. But if both teams are playing good mixed, then that's actually pretty bad strategy, because the woman is probably very close to the net and will probably hit a winner off everything she gets a racquet on. The stronger player will have to be covering more of the court - thus leaving themselves more open and baiting the shot. So in the end, it's actually going to end up about 50-50 in terms of who gets hit to! But it gets to there via adjustment and counter-adjustment from both teams, not by both teams pretending it's standard doubles and then "being nice" by avoiding the right play.
