No, that package is not legit.
You can include phpdocx as any other external library with composer.
This is a quick guide using the namespace package (only for Corporate and Enterprise licenses):
1) Extract the package to the vendor/phpdocx folder
2) Add this line in the autoload option of your composer.json:
3) Update the composer autoloader:
php composer.phar dump-autoload
4) You can use the library:
$docx = new \Phpdocx\Create\CreateDocx();
$docx->addText('This is a test');
