Contrary to the other reply, I'm going to say yes, that's exactly what it means. For Github Copilot users with annual plans that are grandfathered in to per-prompt rather than per-token pricing, Github is increasing the cost of Sonnet from 1 "premium request" per Sonnet prompt to 9, thus meaning that those users will be able to submit 1/9th the number of prompts per month before incurring additional usage charges. For all practical purposes, this is a straightforward 9x increase in price.
