So before parsing, you are getting rid of the "ignoreheading" [fn:1]
headline (first, "promoting" it to a comment and then deleting the
region), so the #+latex: \newpage line now belongs to headline 2
which is then parsed and discarded.

I think you need a filter after parsing (which of course conflicts with
your need in the "Wrong numbering..." thread).

Footnotes:

[fn:1]  there is a "removeheading" vs "ignoreheading" inconsistency,
btw.
