There's no up swipe in the prototype made in 2005 by Ken Kocienda (which this is a reproduction of). It's tap for center letter, and swipe for the sides.

What do you mean by "widen the margins"?

In any case, Ken Kocienda validated this reproduction's behavior as very close to his original blob keyboard (see bluesky posts between him and me)

The goal is not to make it better than the original prototype! But to the contrary, to give you the same experience that pushed Kocienda to explore further and design the right user experience.
