Goldman had written materials about conflicts. Segarra claimed they weren't enough to a "policy" by her opinion. Her boss argued, it was a policy even if it was a really poor one. He didn't tell her to change the report to say they had a policy, he told her to change it to say Goldman's policy was very deficient and need to be improve a lot.
It's essentially a semantics argument, not some huge cover up.
And her boss's stance is arguably more detailed and accurate.
