super and super(...) are method calls in the sense that a method of some
class will be invoked.

super and super(...) are not method calls, in the sense that a true method
call will start a method-lookup, whereas super and super(...) will resume
one.

super(...) is a method call, in the sense that you pass arguments to it.

super is not a method call, in the sense that instead the arguments come
from the enclosing method call.

paragraphs 1 and 2 are due to the nature of super in Ruby/Lisp/Self, which
depend on the class of the receiver (and not the class that the caller is
in, unlike Perl/Java)

paragraphs 3 and 4 are Ruby-specific and so super without args not parens
is just a shortcut for passing *all* same arguments, including the block.
