Since the third person mentioned in the article was "Jeff Jones, who handled physical security", I'm assuming Uber lumped anything possibly related to "security" in one org. Which does seem peculiar.
You are correct. All things with even the vaguest hint of security and safety were lumped there. Antifraud, monitoring who touches which logs, being the sole provider of electronic evidence in all investigations, infosec, competitive information, investigating rapes, putting listening devices into the uber app .....very unorthodox.
