My interpretation is that google is afraid of products being separated into separate companies as a result of antitrust litigation and so is trying to use their branding to support their case that these totally separate services are inseparable.
It's more like building a passive perception of belonging-together over a prolonged period of time, where this is only one step of many, resulting in a subtle shifting of the framing when the discussion happens.
And I can see it, tbh.

I hope they get broken up, because maybe the new Gmail will go back to the older, better logo.
