Two sequences for sec_permission table

I noticed something strange in the DB definitions:

In here there is a table definition (I am using Postgres):

CREATE SEQUENCE ${ohdsiSchema}.SEC_PERMISSION_SEQUENCE START WITH 1000 INCREMENT BY 1 MAXVALUE 9223372036854775807 NO CYCLE;
CREATE TABLE ${ohdsiSchema}.SEC_PERMISSION(
    ID                  INTEGER NOT NULL DEFAULT NEXTVAL('${ohdsiSchema}.SEC_PERMISSION_SEQUENCE'),
    VALUE               VARCHAR(255) NOT NULL,
    DESCRIPTION		VARCHAR(255) NULL
);

But, around the code I see a lot of INSERT statements for other sequence for this table from here, e.g.:

INSERT INTO ${ohdsiSchema}.sec_permission(id, value, description) VALUES
  (nextval('${ohdsiSchema}.sec_permission_id_seq'), 'cohortdefinition:printfriendly:cohort:post', 'Get print-friendly HTML of cohort expression');

Is there any reason there are two sequences for the same thing?
