The instructions don't clarify gender, they are actually contradictory and likely to be confusing. GPT is being told to make "choices grounded in reality" followed by the example "all of a given OCCUPATION should not be of the same gender or race". But many occupations are strongly dominated by one gender or another in reality, so the instruction is contradicting itself. Clearly the model struggles with this because they try repeating it several times in different ways (unless that's being interpolated by the model itself).
You've also got instructions like "make choices that may be insightful or unique sometimes" which is so vague as to be meaningless.

No it's not, it's pretty clearly aimed at avoiding upsetting artists, celebrities and woke activists. Very little in these instructions is about improving quality for the end user.
Some of these rules are protecting OpenAI from liability (don’t do X,y,X).
Things like clarifying gender are going to be helpful in most cases. That can likely still be easily overcome with some prompt hacking.
Ultimately, this is targeted at getting good results for the masses without having to spend a bunch of time tweaking positive and negative prompts.
