Rails - Sep 2013 - [shoulda-matchers gem] validate_numericality_of_matcher strange behaviour

Hello
I have Vacancy model and vacancy_spec test with validates_numericality_of 
:salary, greater_than: 1 in the model and 
validate_numericality_of(:salary).is_greater_than(2) in the _spec.
When i run rspec spec command tests pass (in some cases and in other they 
don''t)
Why?

vacancy.rb
------------------------
class Vacancy < ActiveRecord::Base

  validates_presence_of :name, :salary, :position, :description, :company, 
                        :contact, :location
  validates_length_of :name, :position, :company, :contact, :location, in: 
3..50
  validates_length_of :description, in: 3..250
  validates_numericality_of :salary, greater_than: 1
end

vacancy_spec.rb
--------------------------
require ''spec_helper''

describe Vacancy do

  [:name, :salary, :position, :description, :company, :contact, 
:location].each do
    |value| it { should validate_presence_of(value) }
  end 

  [:name, :position, :company, :contact, :location].each do
    |value| it { should 
ensure_length_of(value).is_at_least(3).is_at_most(50) }
  end 
  it { should ensure_length_of(:description).is_at_least(3).is_at_most(250) 
}
  it { should validate_numericality_of(:salary).is_greater_than(2) }

end
----------------------------------
