Is removal of this code okay?

Hi, recently my website was hacked and a developer investigated and made some changes to my htaccess file. I noticed that the code below has been removed from the htaccess file since then (I am unsure if he did it or not). Is this code necessary for the plugin?

# BEGIN Really Simple SSL Redirect 5.3.5	
<IfModule mod_rewrite.c>	
RewriteEngine on	
RewriteCond %{HTTP:CF-Visitor} '"scheme":"http"'	
RewriteRule ^(.*)$ https://%{HTTP_HOST}/$1 [R=301,L]	
</IfModule>	
# END Really Simple SSL Redirect
