ACS positive but have a simple but important question

Hello,

I got a positive ACS with following details:

Skills found to be positive for Software Engineer.
Satisfied ACS requirements as per PIM 3 policy class A.

Skill employment is calculated as below:

Date: 08/06-04/10 ( 3 years 8 months)
postion : Software engineer.

Date: 05/10-03/11 (10 months)
Position: Managed Services Associate

Dates: 03/11-08/11 ( 5 months)
Position: System Analyst

Question: AS per the above details, is my experiences assessed to be valid for 5 years or for 3 years? . Meaning, does ACS put all the experience (valid and invalid) in their letter or do they put in only valid experience in their assesement letter. Since, my job title for my 2nd and 3rd company is not Software engineer, I just want to confirm.

Thanks for your time!
