Female pronouns are used in many contexts to counteract the too-common use of male pronouns. I assume jubos was doing this because he knows the tech-world is flooded with male pronouns.
I have no problem with this in general... but for the love of god, please don't do what a coworker of mine did recently. In a threat model document, he had A sending HIS messages to B, using HER public key. I automatically translated the names to Alice and Bob (like anyone else would in a threat model), hit the pronouns, and my brain segfaulted.
