Yes, that is correct.
FSW is one of the three programs managed through the Express Entry system. The other two are the Canadian Experience Class (CEC) and the Federal Skilled Trades (FST) program.
To apply for any of these two programs, there are two steps:
1) You must meet the minimum entry criteria for (at least) one of the three programs (this will allow you to create an EE profile)
2) You must then have enough CRS points to receive an Invitation to Apply (ITA). If you do, you are allowed to apply for the program you were invited for (FSW, CEC or FST).
CRS points are only relevant for step 2. Your Canadian experience won't help you for this, as discussed.
But I thought it might help your for step 1. Suggest you read about the minimum criteria for FSW and the FSW selection grid:

The second link explains the FSW selection factors. Refer to heading "work experience".
Unfortunately I just realized / remembered that you would get the same amount of points for both 2 and 3 years of work experience, so unless you have any additional work experience in the last 10 years, those 2 months of Canadian experience you were talking about indeed seem to be of no use to you.
