Because in tight "shieldwall" formation = overhand grip makes sense (no sandwitching, you can freely jab from above)
In other formations = overhand grip is an amazing way to get killed
Medieval eh? Medieval fomations could be as compact as phalanx formations. Just think of the Anglo-Scandinavian shield wall.
However, it doesn't mean that the overhand spear grip was used exclusively in tight formations.

If you do that, you make the spear tip heavy. That tires you more quickly, makes your attacks slower and allows your opponents more chances to move past your spear, knock it aside or just outright grab it from you. Also, you are still limited by your shield and the shield to the person next to you. Lastly, no one would hold the secondary spear head close to their skin - that's a self inflicted wound waiting to happen.
Medieval manuscripts leave a bit of the shaft sticking in the other end.

Spears are dirt cheap but ALSO amazing. Just not so good in close quarters... hence the overhand grip making sense, but only then
You cannot take shields out of a discussion about spear&shield combat. I really can't stress that enough. They are such a huge game changer- they are the main reason we're having this discussion.
Reach can be a great bonus, but it's not the main quality of the spear. Just look at Zulu spears. They are short. That's because their style of melee fighting relied on closing the distance and stabbing the enemy.

High/mid/low with the underhand is trapped by your shields and it strikes right into the enemy's shield, armor, greaves. In a fight, wasting energy and opportunity is extremely dangerous.
On the other hand, overhand focuses on moving past defensive gear and striking the vulnerable areas of the body.

With the underhand spear grip, you get 1m of extra reach at the expense of speed, power, your ability to easily operate the weapon in close quarters etc. Your opponents know you can't throw the spear in that position, so they are less concentrated on you.
With the overhand grip you are able to throw the spear at any moment - that's up to or even perhaps more than 10m of extra reach, depending on the spear and the strength of the thrower. That's a considerably greater risk to the enemy. In my opinion, that's a better form of active defense.

I'm glad we're having this discussion. Like I said, I wasn't a fan of the overhand grip when I started getting interested into ancient and medieval history. Time and experience changed my views.
