LaTeX manuals don't tell all you need for this,
often you need the TeXbook indeed

In this case, I guess the \vspace12pt causes the break

My suggestion was not that you can prevent the page-break
just by that \@beginparpenalty10000, but that it is /necessary/
-- among other things -- or can help, together with other things.
Especially, the \@beginpenalty thing still requires \nopagebreak.

Oh -- and I see: you haven't understood me:
the \@beginparpenalty thing must be done in the
