What's up with ball spots on penalties?

[d10]

I know there have been a lot of rule changes in the NFL this year and I'm not familiar with all of them, have the rules on spotting balls after penalties changed?

First I see Jeff Saturday of the Colts holding at the 2 yard line, line of scrimmage was like the 8 yard line or something (completely guessing on that but it was around there) and the ball is spotted 10 yards from the spot of the hold, back to the 12 yard line. I don't remember ever seeing that before, it's always been 10 yards from the line of scrimmage for offensive holding.

Next I see Daunte Culpepper step back to the 21 yard line and throw the ball away short of the LOS, called for intentional grounding, loss of down and the ball spotted at the 21 yard line. WTF? That's not even a penalty anymore, the result would have been exactly the same as if he had just taken a sack.

I'm not losing my mind am I? These spots are different than they would have been in the past?
