Ch.5, p.55 - Incomplete spec?

This is more a question than an actual issue.

In the spec on page 55, does the saves the new contact in the database test really test that the new contact is saved?:

it "saves the new contact in the database" do
  expect{
  post :create, contact: attributes_for(:contact, phones_attributes: @phones)
  }.to change(Contact, :count).by(1)
end

In my opinion this test does nothing but test that some contact is saved (and thus should really be named saves some new contact in the database). The saved contact could be any valid contact, but there's nothing that checks the saved contact is actually the one submitted. Should we not test this?
