You can't go back on neutral runs, and the only difference is that the barrier is still there. Which is contradictory to the statement that anyithing can go in, but you need soul power to leave. Which in turn is contradictory to that you can fall down but monsters don't leave through the hole. Because they have jetpacks and flying robots, and some can fly themselves, and if you really can't cross the barrier from any direction, Frisk and Chara should have stopped falling somewhere mid-air.

Also, they don't bring you to the flowers. There are no flowers, only a green patch with light around it, and they bring you back to the room before the barrier, and not the one where the barrier used to be.

Exactly. Tsunderplane, Madjick, Mettaton, and MAYBE even Undyne (spear ladder) would know what the outside was like judging by this logic.
