After a creature makes a Dex save from Wall of Fire, does it end up inside or outside the ring?

Question

Let's say a Wizard casts Wall of Fire in the ring shape, choosing the inside of the wall as the side that does damage.

An enemy is in one of the squares on the edge of the ring (ie. one of the 8 squares on the outside of the template for a 20' diameter circle, and not the 4 inner squares). Therefore, the enemy must make a Dex save and might take 5d8 damage.

If it makes the save, is it inside the ring?

If it fails the save, is it inside the ring?

Here is a good reference for the way the damage works: Ringed Wall of Fire: How does the damage sequence go?

Answer 1

Creatures do not move when making a saving throw against wall of fire

The wall of fire spell states:

[...] When the wall appears, each creature within its area must make a Dexterity saving throw. On a failed save, a creature takes 5d8 fire damage, or half as much damage on a successful save [...]

One thing we know is that spells do only what they say they do and wall of fire does not say that creatures move after attempting (succeeding or failing) its saving throw. Thus they do not move.
