Github copilot outbound flow clarification

Question

in this training page, https://learn.microsoft.com/en-us/training/modules/introduction-prompt-engineering-with-github-copilot/3-github-copilot-user-prompt-process-flow

the outbound flow shows LLM -> Proxy server -> Toxicity Filter -> Code editor

somehow the explanation contradicts that.

"Once the model produces its responses, the toxicity filter removes any harmful or offensive generated content. The proxy server then applies a final layer of checks to ensure code quality, security, and ethical standards. "

Can you clarify sequence of the steps? The response goes through proxy server then toxicity filter, or go through toxicity filter and then proxy server?
