ExcelCreatBook pops up even when set to be invisible

[kor]

$book = _ExcelBookNew(1)
_ExcelWriteArray($book, 1, 1, $staffheaders)
_ExcelWriteArray($book, 2, 1, $staffdata)
_ExcelBookSaveAs($book, @ScriptDir & "\Temp.xls", "xls", 0, 1)
_ExcelBookClose($book)

Even though the visible tag is set to 1 to make Excel not visible, it still pops up and I can see it. Is that normal behavior?

1 = default, visible

0 = not visible

1 = default, visible

0 = not visible
