If the hole is small it will seal it self while riding. Saw this other day when someone was riding a gravel bike. A bunch of orange sealant spurted out. A few seconds later it stopped. Tire still full of air like magic.
If you still hear and see it leaking, you want the hole on the bottom where all the liquid sealant can pool and cover the hole.
I am not sure how putting the hole on top with your finger on the hole and all the sealant pooled at the bottom of the tire would do anything.
