talking of being SARGable, i was reading this article:

http://en.wikipedia.org/wiki/Sargable

and didn't quite understand this line

The typical thing that will make a sql query non-sargable is to include a function in left part of a condition of a Where clause.

one of the examples given was:

Non-Sargable: Select ... WHERE DateDiff(mm,Date,GetDate()) >= 20

does that mean that if it was written like so:

Select ... WHERE 20 < DateDiff(mm,Date,GetDate())

that it would be Sargable, as the function is now on the Right hand side of a condition in a where clause?
