-    # we do this as the gender same as sex page always contains the gender description box that's hidden
-    # default submit will send a "" for gender description. this ensure it's nil in this case
-    # as well as blanking it if the user writes it in mistakenly in bulk upload
+    # gender_description is always routed to (even when hidden on the page), so default submit will set it as ""
+    # This method ensures gender_description is cleared if gender is the same as sex
+    # This also has the benefit of clearing a mistakenly input gender_description in bulk upload if gender is the same as sex
