No. The difference is that t3lib_div::debug does not return anything but
echoes the debug content. Therefore the debug output is written before the
first character of generated HTML has been sent by TYPO3 (= it is outside
of the document body, see subject).

t3lib_div::view_array is exactly what was needed because it returns the
debug content to the calling function.
