FWIW, here you add `problem-show-end' buffer-locally for NEWS.

Here NEWS is the current buffer and the actual value gets reported.

> (switch-to-buffer (get-buffer-create "test"))

Here NEWS is no more current, no value gets reported.

> ;;; problem.el ends here ;;;

What you see is the value reported after splitting the window not after
enlarging it.
