Does anyone know what the black metal pipe directly in front of the passenger front lift point is? First time in 20 years I've had a car slide off the jackstands and it pinched this pipe not a good day. Same thing happened on the drivers side and it pinched the clutch hard line which is $250 part.
When you jack up a 997, you should have something that locks into those holes in the jackpoints to prevent this like these. They go into the oval holes and turn 90 degrees to lock into them
Also, you should not be using saddle jacks unless also using them with lift bars. If you've never heard of lift bars, check them out as they make the car easy to get into the air and you can jack up a whole side without twisting the chassis at all. You jack from the center (white stripe) of the bar and them place the jack stands at the ends. I have some under my 928 in this pic on the bridge Jack's on the 4-poat lift. The top side has pins that go into the jackpoints holes.
Also a good idea once youve put the car into the air to push on it and wiggle it to make sure it's secure before getting under it.
The hard line you're referring to, without looking, is probably a coolant line.
I had the front factory lift points centered perfectly on the jack stands on the lowest setting and then began jacking up the rear from behind on the car. As I was lifting the rear to level the car out it gradually pulled the car back it seems about two inches off of the front factory jack points onto the plastic shields and underbody. The car stayed in the air it just pinched the clutch hardline and a coolant metal pipe. I wasn't under the car thankfully and it didn't damage the underside of the body of the car.
Regarding sliding... I suspect.... looking for comment here.... that a hockey puck between a jack and the chassis will prevent sliding no? Those metal pucks with the locking tabs... sure they won't slide between them and the chassis, but what about the jack? It is the metal-to-metal contact I worry about.
When I jack up high, I get weirded out all the time no matter what.
Also, having your tires locked with emergency brake and chocks is important to prevent sliding.

What do the top of your jack stands look like? Are they flat ... flat with rubber or metal-to-metal contact... or those "U" shapes (axle mounts) I see on most stands? And, did you put something in between the jackstand and the chassis like a hockey puck?
When the car slid.... what should happen, is the jack should roll on its wheels as the angles are not straight up and down (I keep mine greased), not the car move. Was your floor smooth enough for the jack to roll? Was the jack lined up to roll straight back and forth or did you have it at an angle which would cause the jack to resist rolling?
