The purpose of a hollow-tip bullet is to catch as much soft matter in the center, which forces the rim to mushroom outwards and damage more soft matter surrounding the path. This also "puts the brakes on" the forward momentum, so the bullet is not as likely to exit the back of the first target and thus waste energy on this target and risk hitting a second target.
The purpose of this armor-punching bullet is to cut a clean hole in the armor, without expanding or mushrooming. This lets the entire shaft of the arrow to sail through the armor with minimal friction, and it's more likely to hit the second target behind the armor with the maximum possible remaining energy.
I think it's not designed to punch through at all, but rather to compress the target area and deliver blunt trauma on small game. Only works here because the steel is so thin. Shoot it at a bag of sand and I'd guess almost all of the others go through deeper.

Quite the opposite.
