Hmmmm. Maybe down the road if doing PRAM doesn't do the trick for good. I didn't know I could follow steps and go just so far and then stop.
Ordinarily, I wouldn't advise stopping in the middle of a procedure, but this is two separate procedures, and I don't seriously think a reinstall is necessary in your instance.
Of course, if you shut down your MBP regularly you can just do PRAM every time you fire it up, and that will probably perpetuate the fix.
