AdventureWorks SQL conflicting results issue - tsql

Question

I'm working with the AdventureWorks example DB - we're running SQL Server 2008R2, so I assume that's the edition of AdventureWorks (I have read-only access). I'm trying to get a list of sales managers so that I can then determine a couple employee/manager relationships.
I'm getting two sets of three differently named people, with the same job title, with their CurrentFlag set to 1 (active) with slightly different queries. I do notice that one result group has the same contactID and employeeID, but I'm not sure what this may indicate.
So the question is: Why am I getting completely different results with these two queires? I would think I'd get six results for each - the queries are matching employee table Titles.
SQL Query 1:
select
c.FirstName,
c.LastName,
c.ContactID,
e.EmployeeID,
e.Title,
c.Title,
e.CurrentFlag
from Person.Contact c
inner join HumanResources.Employee e
on c.ContactID = e.ContactID
where
e.Title like '%Sales Manager%'
SQL Query 2:
SELECT
e.EmployeeID,
(c.FirstName + ' ' + c.LastName) as 'First Name and Last Name',
e.Title
FROM HumanResources.Employee e
INNER JOIN Person.Contact c
ON e.EmployeeID = c.ContactID
Where
e.Title LIKE '%Manager%'
AND
e.Title LIKE '%Sales%'
ORDER BY e.EmployeeID;
UPDATE: These are my results:
SQL Query 1:
------- ------- ---- --- ---------------------------- ---- --
Stephen Jiang 1011 268 North American Sales Manager NULL 1
Amy Alberts 1013 284 European Sales Manager NULL 1
Syed Abbas 1012 288 Pacific Sales Manager Mr. 1
SQL Query 2:
--- --- ----------- ---------------------------- --- --
268 268 Gary Drury North American Sales Manager Mr. 1
284 284 John Emory European Sales Manager Mr. 1
288 288 Julie Estes Pacific Sales Manager Ms. 1

Answer 1

The only diffrents i can see is this:
where
e.Title like '%Sales Manager%'
And this:
Where
e.Title LIKE '%Manager%'
AND
e.Title LIKE '%Sales%'
The first query says that bring me all titles that has '%Sales Manager%' you can have for ex this output:
Account Sales Manager
some Sales Manager
Sales Manager something else
The second question says bring me all the titles that has '%Manager%' and '%Sales%' so you can for ex have:
Sales Account Manager
some Sales some Manager some
Sales Manager some else thing
Manager Sales
And this join can not be corrent
INNER JOIN Person.Contact c
ON e.EmployeeID = c.ContactID
Don't you mean:
INNER JOIN Person.Contact c
ON e.ContactID= c.ContactID

Answer 2

The first query will match the rows where substring "Sales Manager" is present. But second one can match rows like "Managers of Sales Dep" as well. I mean the second doesn't care about positions of the words in the srting.
I believe that the results of first query is a subset of the results of second one.
UPDATE
You use different columns in JOIN clause, so it's normal that you got different results.
