From the article you linked:

In return for Google being the default search engine in Firefox, Mozilla is expected to bank $400M+ a year.

Literally what I am talking about. I can still switch away from the default. No other search companies are being denied access to being set as the default search engine in Firefox. Google just pays a premium so they are the default out of the box, which would not be anti-competitive under this order.

bar the search giant from making exclusive deals to distribute its search or AI assistant products in ways that might cut off distribution for rivals.

This by definition does not cut off their distribution in Firefox. Google can still make this deal with Mozilla. It is not an exclusivity deal, it's a default search engine deal. Exclusivity or cutting off distribution would be making Google the only search engine option in Firefox.

Thank you for clarifying.
