The keycodes identify the key which is pressed. The value depends
on the hardware (e.g. USB vs. PS/2) and layout of the keyboard.

The keysym corresponds to the meaning of the key. In both
cases the application sees the "arrow down" (== Down) and
the "page down" (== Next) keys.

Behaviour on Linux (Debian 12) and NetBSD (-current), both open
on the same X display, is almost the same.

Only when you view a partial page, scroll down with the Down
key to the page end, the next step goes to the beginning of
the following page (Linux) or the end of the following page (NetBSD).

On Debian it's mupdf 1.21.1+ds2-1+b4
On NetBSD it's mupdf-1.24.10nb4

That's probably where the different behaviour comes from. A
quick search however didn't show any known bugs in that area.
