Difference between box's region & atoms' region

Hi my friends!
I am using LAMMPS to simulate an eam system recently.
Can create_box ’ region be larger than create_atoms ’ region??

units metal
atom_style atomic
boundary s s s
lattice fcc 4.0500

region simbox block -300 300 -300 300 -300 300 units box
create_box 2 simbox

region cube block -30 30 -30 30 -30 30 units box

create_atoms 1 region cube
