Firstly it is extremely unlikely that the landing you experienced was anywhere near the structural limit of being classed as a "hard landing".
Secondly as others have said for a 5,700ft runway a firm touchdown on the aiming point is highly preferable to minimise stopping distance.
If you're at O'Hare or something there's not so much need for that and the pilot can make a softer touchdown, maybe float it a bit beond the aiming point since the runway is nice and long. At SNA
that is not a consideration.
But like I said before, an official "hard landing" (one that requires post-flight inspection of the landing gear) is very very hard indeed. I have absolutely smacked the 757 / 767 down before and still been nowhere near the limit. The aircraft can take it.
I used to love the smell of Jet-A in the morning...
