I think you missed one other issue - does the ancestry.com search engine highlight both names of a married couple when it finds both common ancestors (not related to whether it is in fact a DNA match to both - it may or may not be) but will your screen show both names as a shared ancestor "hint" (the pale blue horseshoe with both trees highlighted in a U-shape). Until about 3-4 weeks ago, it did not -- since then, it does show them "sometimes" but not always.

Otherwise, we are on the same page re gender and autosomal DNA - I thought the questioner might also be asking about how ancestry.com is showing results and if you were in the beta phase, you might have notice this recent change (noted in some earlier threads when it first started appearing). But it still isn't consistent...
