No, this is expected (if possibly under-documented behavior).  The
:results header arguments are associated with the code block and *not*
with the #+call line.  To get the desired behavior, you must specify the
:results header argument on the #+call: line thusly.

#+call: print_list(lst=list1) :results output org
