Cross Apply question using SQL Server 2008 R2

I'm following along with a video by Ben-Gan called Creative Uses of Apply Operator and he shows this code

Select orderiid, orderdate, nextyear
from sales.order
  cross apply(values(year(orderdate))) as a1(orderyear)
    cross apply(values(year(orderyear +))) as a2(nextyear)
where orderyear > 2007

---end code----

He comes up with a result set where the nextyear column is one year later than the orderdate, i.e., if orderdate is 2008-01-01, nextyear is 2009
you can see it video place...

However when I try using it with this code on two different databases 2012 AdventureWorks or AdventureworksLT  I use the same code on different column names..


select SalesOrderID,  OrderDate, NextOrderYear
from SalesLT.SalesOrderHeader
      cross apply (values(year(OrderDate))) as a1(orderYear)
            cross apply (values(year(orderYear + 1))) as a2(NextOrderYear)
            where orderYear > 2001

I get the

 NextOrderYear as being 1905

Obviously something is not right. Just not sure what?
