You say “all else equal” here. But all else clearly isn’t equal—they have different genders.
You assumed that Alice was a girl (normally a good guess), but I never mentioned his gender in my thought-experiment. Then again, they have different names, etc...But this misses the point of my “all else equal” clause, which refers to their interestedness and succesfulness (besides their (probable) success at deadlifting), not a myriad of accidental features.
