Since nobody replied and I think it's an interesting question,
does anyone know why this happens?

elathan@velka:~> cat gm.rb
module A
	attr_accessor :val1
	attr_accessor :val2

	def initialize
		@val1 = @val2 = "A"
	end
end

module B
	attr_accessor :val3
	attr_accessor :val4

	def initialize
		@val3 = @val4 = "B"
	end
end

class MyClass
	include A, B
	def initialize
	    super	
	end
end

class MyClass2
    include A
    include B
    def initialize
        super
    end
end

p MyClass.new
p MyClass2.new

elathan@velka:~> ruby gm.rb
#<MyClass:0x401cc1c4 @val2="A", @val1="A">
#<MyClass2:0x401cc0e8 @val4="B", @val3="B">
elathan@velka:~> ruby -v
