They probably don't mention it because they aren't measuring that statistic. If you want to see how likely it is that people will name their male babies "female" names you could probably do that, but you couldn't do that by looking at the "most switched" names from a popularity standpoint. In particular, naming your male a "female" name (or vice versa) that has not switched would really do a better job at showing what society thinks of this. Especially because a singular event in pop culture can switch the public perception of the gender-ness of a name: e.g. the election of John F Kennedy turning "Jackie" into a "female" name practically overnight.
