rdoc indicates that Method#owner will return a class or module that defines a method.
http://www.ruby-doc.org/core-2.0/Method.html#method-i-owner

---

module MyMod
def x(y)
super(y*y)
end
end

class Blah
def x(y)
y + 1
end
prepend MyMod
end

Blah.new.method(:x).owner
# => MyMod

---

In this case, a class or module that defines a method is Blah.
So I think Blah.new.method(:x).owner should return Blah.

I don't catch your point.
Blah.new.x(1) calls MyMod#x, so Blah.new.method(:x).owner should return MyMod, shouldn't it?

Also for me, this is the expected behavior. MyMod is prepended before Blah, and therefore Blah.new.method( :x ) is taken from MyMod. As soon as you perform module MyMod; remove_method( :x ) end, method x will be again taken from Blah.
