Mars has isolated pockets of "mini magnetospheres" that are suitable enough to block charged particles.

I think he was assuming the subject was terraforming.

Without a magnetosphere, the atmosphere will keep being blasted off into space continuously, and it'll be impossible to terraform.

Continuously, but slowly, over very long time scales. Maintaining an atmosphere suitable for us is probably far easier than constructing it in the first place.
