Stop drilling cracks, why do we go so deep?

I'm just wondering why we go so deep on stopping cracks, and also why cracks can't jump past the drill point?

It seems to me that it's the same as a chip, you scribe into it a little bit and fill it, the resin travels out to the tip.. repair good!

Why can't we drill into the end of a crack, on the top of it, just a little bit down so resin can travel into to, and fill to the end?

Just wondering why it matters to get in front of a crack, when that's not needed at all for legs sticking out of a chip.. Seems like if the crack jumps past it would still fill in. Also, seems like it would fill in fine too without drilling so deep!! ...Just drill as much as a regular chip somewhere on the crack and start filling. This wasn't how I was trained but I am very curious as to the thinking behind the extra steps that are taught! Thank you!!!

I do not drill deep, I drill and pop beyond the end of the crack, I then break the crack into my stop. It adds strength to a long crack and also enables us to see exactly where the cracks ends.
