Install Roles and Features Behavior MDT 2013

Question

I'm setting up a Task Sequence in MDT 2013 to try out installing Windows 8.1 for the first time. We need to add .NET Framework 3.5 so I thought I'd add a Install Roles and Features step in the State Restore section to take care of that.
When I kick off the Task Sequence, I now see a new dialog that shows the Install Roles and Features for me to choose from. Didn't I just create a step for this? Why is it showing up asking me for my choices when I already specified what I needed? I thought
maybe I messed up adding the step in my Task Sequence but after checking, it's still there enabled. Will .NET try and install twice now?  I have never seen the new dialog before.
After some testing I found that if I disabled the step I added, I no longer get the Install Roles and Features dialog at the beginning. Is this expected behavior or am I missing something?

Sandy, this is known behavior when adding Roles and Features from the task sequence. Leave your TS step as is and add
SkipRoles=YES to the customsettings.ini file.
