No, first of all, there is a screenshot in the article showing high memory pressure. That needs to be taken into account by your analysis of the author's intentions and understanding.
Second, I have one of the new new systems with a lot of RAM and when WindowServer takes up 20-30GB of RAM, and other apps take up 2-10GB more than they should, I see high memory pressure. There are other reports of this. Don't extrapolate too much from one screenshot showing a system shortly after reboot.
It's possible that most of the bloat from this bug gets pushed to swap and harmlessly stays there until reboot, to leave space in DRAM for actually useful application memory, but the typical user doesn't have guarantees of this based on the instrumentation available to them.
