Role licensing - Community edition

im not quite sure if im understanding this right:
community edition is limited to 5 roles... (platform v. 7.0.0.7 btw)

so now i created an espace, with 2 modules.
by default there are already 2 roles "Anonymous" and "Registered".
in espace 1 i created an "Admin" role,
and in espace 2 a "Manager" role.

now in the licensing section, it states that im using 5 of 5 roles.
can someone explain that to me?

are the standard roles calculated 2ce? and why?

i dont understand how one should follow the guidelines,
and split everything nicely to different espaces/modules,
if the role limit is already reached with 1-2 modules..

thank you!
