Well, if you ask me, the people who are careful about this believe that *any* casual interaction between an unrelated male and female, married or single, is inappropriate, whether it leads to spousal comparison or not. They just frown on intergender socializing, period.
Yes, but for somewhat different reasons and with different sets of rules. For example, let's say Nechama Dina and Sender have a policy of avoiding mixed gender social interactions. The reality is that in spite of that policy, they would likely be more likely to have their married friends for shabbat lunch rather than a gaggle of Beis Rivkah babes at the same time as a covey of Morristown dudes. Secondly, if the reason were limiting social interactions, then there wouldn't be different rules for shanah rishonah couples than for longer married couples.
So while I realize many frown on intergender socializing, it's not so black and white, but there are caveats and exceptions and gradations to that general rule, and one of the factors that influence the final decision is apparently, at least for some, whether it could lead to spousal comparisons, something arguably possibly more likely for relatively newlyweds.
