The temporary border controls are not there to physically stop people from entering, but to dissuade them from trying to go to Norway at all in the first place. That's the big effect, and it is of course intentional.
This ended up in a huge mess, but as far as I know very few were actually turned away. Mostly people ended up being fined for not being able to provide a valid ID and let back in after a manual verification. There were some controversy around this, as citizens are not legally required to carry IDs.
