Well the FCC approved them for 2Ghz of bandwidth for downlink from
satellite to user terminal. This is separate from the satellite to
ground station bandwidth.
If they've lit up a certain area with their whole 2ghz, does it matter
if they have more satellites?
Similar to if you have hit the same city block with every 5ghz channel,
what good does it do to add more 5ghz APs aimed at the same block?
Maybe they have that figured out. I'm just wondering.

The difference has got to be with the number f ground stations. Unless
my understanding is incorrect, Geo-synchronous satellites have one
ground station per satellite. Starlink will have lots of ground
stations with traffic split between them Certainly not 12,000, but
perhaps one ground station per every two or three rings? I'm guessing
they could add ground stations in areas with a lot of traffic as well?

A graceful hand-off might only give you a brief moment of jitter.
My skepticism is directed at capacity. I haven't seen how 12,000
satellites gives you 12,000X capacity like some people seem to
assume. Once you've used every channel in a certain area then you
don't get more of them no matter how many more AP's you install.
Maybe the plan is after you Hughesnet's lunch you buy them out and
use their channels too. Repeat with Viasat etc.

"Initial results have been good," she said. These tests reveal
"super-low latency," and download speeds greater than 100 megabits
per second. This, she noted, would provide enough bandwidth to play
the fastest online games and stream multiple HD movies at once.
I'm wondering what happens when it needs to swap to another dish,
the tracking will need to change fast and that delay would probably
kill any gamers in the heat of battle :)
