And that 'ref' is necessary because not every OutputRange can be sliced for further calls to put(). Salih does not have that problem because he is working with slices, which are (usually) trivially slicable for the next portion to be passed to put().
On the other hand, Phobos's put() works with any OutputRange so it has to take a 'ref' to advance to know where it is left off. This behavior makes its use with slices weird but sometimes such is life. :)
