  static checkEmails(group: FormGroup): ValidationErrors | null {
    const email = group.controls.email.value;
    const confirmEmail = group.controls.confirmEmail.value;

    const responseKo = { NOT_SAME: true };
    const responseOk = null;

    let identical = false;
    if (email.toLowerCase() === confirmEmail.toLowerCase()) {
      identical = true;
    } else {
      group.controls.confirmEmail.setErrors(responseKo);
    }

Just use a form validator for that ? 

const emailChecker = (form: FormGroup) => {
  const email = form.get('email').value;
  const confirm = form.get('confirm').value;

  return email === confirm ? null : { emailConfirm: 'Email confirm mismatch' };
};

// ...

this.form = this.builder.group({ ... });
this.form.setValidators([emailChecker]);
