   “Return: (bool|string) False on failure and string of headers if HEAD request.” – this is said in above documentation.

   But, it never returns string; instead returns array containing header info. Noting it here, as i think this is not a wordpress code bug (according to code it should be array return in case of header and ofcourse array is more useful in the scrnario of get full header info), instead a documentation typo, may be.
