An object's methods don't have an order.

irb(main):001:0> class X; def y; end; end
=> nil
irb(main):002:0> X.instance_methods(false)
=> ["y"]
irb(main):003:0> class X; def z; end; end
=> nil
irb(main):004:0> X.instance_methods(false)
=> ["z", "y"]
irb(main):005:0> class X; def b; end; end
=> nil
irb(main):006:0> X.instance_methods(false)
=> ["z", "y", "b"]
