A nested join is indented additionally relative to the join that it is nested within:

SELECT *
FROM Person.Address
--INNER JOIN Person.StateProvince
----INNER JOIN Sales.SalesTerritory
------ON SalesTerritory.TerritoryID = StateProvince.TerritoryID
----ON StateProvince.StateProvinceID = Address.StateProvinceID

When joining the same tables but not writing them in a nested manner, there is no additional indentation:

SELECT *
FROM Person.Address
--INNER JOIN Person.StateProvince
----ON StateProvince.StateProvinceID = Address.StateProvinceID
--INNER JOIN Sales.SalesTerritory
----ON SalesTerritory.TerritoryID = StateProvince.TerritoryID

It would be nice to allow the same amount of indentation that would be used if the join were nested to be used when it is not nested:
SELECT *
FROM Person.Address
--INNER JOIN Person.StateProvince
----ON StateProvince.StateProvinceID = Address.StateProvinceID
----INNER JOIN Sales.SalesTerritory
------ON SalesTerritory.TerritoryID = StateProvince.TerritoryID
