Did my crank gear slip...?

Ok, So I noticed that my (Intake) valve is starting to press down on its valve before the piston reaches the top as the exhaust leaves the chamber. I understand that the cam is set up to open up the (exhaust) just a bit to help with the pull start. But this is on the intake side. Or am I looking at "Overlap" and just thinking to much?
