This is indeed a riddle. But is there a hard reason not to insert
stat "$out" >/tmp/stat_out_after_creation 2>&1
after that line and to compare /tmp/stat_out_after_creation with the
stat(1) result when the expected file appears 30 seconds later ?

So you are supposed to really know what it does. :))
Whatever, it is fewly plausible that the file would not show up in stat(1)
or ls(1) but the script can happily do
... >> "$out"
Each of these lines is supposed to do a name lookup of the file.
Maybe another stat(1) should be placed between
printf "OK, output in %s\n" "$out"
and
exit 0
Have a nice day :)
