Wordfence addition to htaccess

Hello,
I have 3 sites currently using Wordfence, and to the best of my knowledge all 3 are setup the same. All three show the Firewall setup with: “Extended Protection” along with “Enabled and Protecting”.

Only 1 of the sites htacess file has the following:
# Wordfence WAF

<Files ".user.ini">
<IfModule mod_authz_core.c>
	Require all denied
</IfModule>
<IfModule !mod_authz_core.c>
	Order deny,allow
	Deny from all
</IfModule>
</Files>
# END Wordfence WAF

Is the above above code for Wordfences firewall? If so, why does only 1 htaccess file contain that code?
Thanks
Clint
