Let me remind that the discussion originates from a complain that
filling paragraph does not respect ^L character in the .org file. The
topic starter have not provided more details concerning their use case,
maybe it is irrelevant to export.
During export (LaTeX is not the only case, even HTML may be printed or
saved as PDF and has some CSS attributes) \clearpage (or its equivalent)
may be attributed to the end of a block level element or a beginning of
it. In the latter case it should be preserved even if the previous
heading is commented out. It resembles to a recent topic discussing
wrapping exported heading or other elements into some template.
I agree that page breaking inside paragraph (at particular point or when
current line is filled) is a different case. Degree of support may vary
across export backends.
