Rspec before(:each) works but before(:all) does not

My ProductCategory spec:-

require 'rails_helper'

RSpec.describe ProductCategory, type: :model do
    before(:each) do 
        @product_category = create(:product_category)
    end

  context "validations" do 
    it "should have valid factory" do
        expect(@product_category).to be_valid
    end

    it "should have unique name" do 
        product_category_new = build(:product_category, name: @product_category.name)
        expect(product_category_new.save).to be false
    end
  end
end

The spec runs fine, but when I use before(:all) instead of before(:each), second example fails -
expected false got true I know the difference between before(:all) and before(:each) but I am not able to find the exact reason why second example fails with before(:all)

before :all only runs once before all the examples, so the @product_category is created once. If you have a something like a DatabaseCleaner truncation running after each test, the record is no longer in the database in the second test, thus passing the validation.

before :each on the other hand will be run before each example, so the record will be there in the second example even if the database was cleaned in the meantime.
