According to [official Microsoft BOL][1] DENSE_RANK is nondeterministic ([RANK()][2]). But according to [Ranking Functions by Itzik Ben-Gan][3]  "... the RANK() and DENSE_RANK() functions are always deterministic". Who is right?

What I have found so far:
[Microsoft's Definition][4] "Deterministic functions always return the same result any time they are called with a specific set of input values and given the same state of the database."

So in Set theory tables
Employees

    Employee	        Salary
    Sue Right	         1.00
    Robin Page	         1.00
    Phil Factor	         1.00

and
Employees2

    Employee	        Salary
    Phil Factor	         1.00
    Sue Right	         1.00
    Robin Page	         1.00

are the same. But Ranking functions return different values:

    CREATE TABLE [dbo].[Employees](
    	--[ID] [int] IDENTITY(1,1) NOT NULL,
    	[Employee] [varchar](150) NOT NULL,
    	[Salary] [smallmoney] NULL,
    ) ON [PRIMARY]
    
    GO
    CREATE TABLE [dbo].[Employees2](
    	--[ID] [int] IDENTITY(1,1) NOT NULL,
    	[Employee] [varchar](150) NOT NULL,
    	[Salary] [smallmoney] NULL,
    ) ON [PRIMARY]
    
    INSERT INTO [dbo].[Employees]
    ([Employee] ,[Salary])
    VALUES
    ('Sue Right', 1)
    , ('Robin Page', 1)
    ,('Phil Factor', 1 )
    GO
    INSERT INTO [dbo].[Employees2]
    ([Employee] ,[Salary])
    VALUES
    ('Phil Factor', 1 )
    ,('Sue Right', 1)
    ,('Robin Page', 1)
    GO
    SELECT RANK() OVER ( ORDER BY Salary) AS [Rank]
    , DENSE_RANK() OVER (ORDER BY Salary ) AS [Dense_rank]
    , [Employee]
    FROM
    dbo.Employees
    
    SELECT RANK() OVER ( ORDER BY Salary) AS [Rank]
    , DENSE_RANK() OVER (ORDER BY Salary ) AS [Dense_rank]
    , [Employee]
    FROM
    dbo.Employees2
    
    SELECT NTILE(3) OVER ( ORDER BY SALARY )
    , [Employee]
    FROM
    dbo.Employees
    
    SELECT NTILE(3) OVER ( ORDER BY SALARY )
    , [Employee]
    FROM
    dbo.Employees2
