I've noticed that on nearly ALL of the days I hit the snooze button 10 or so times before getting up, I experience impaired memory, cognitive function, feeling not like myself, etc.
The impaired function is probably not due to lack of sleep because for the same amount of sleep I don't feel adverse effects when I get up right away.

Anyone have a possible reason as to why hitting the snooze button many times ruins cognitive functioning?

Are you so sure that this is a cause-effect relationship? So far, all you have demonstrated even anecdotally is a correlation, and the confusion of correlation with causality is one of my pet peeves in the world of research.

Perhaps the days when you keep hitting the snooze button are the days when you are already experience cognitive disfunction, and hitting the snooze button is simiply another symptom of that feeling?

Over sleeping in general makes me groggy for the first half of the day.  The post above is probably on to something with the correlation over causation possibility.
