.htaccess RewriteRule - Difference between [L,R] and [R,L]?

Question

Is there any difference between flag [L,R] and [R,L] e.g:

RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} !newdomain.com$ [NC]
RewriteRule ^(.*)$ http://newdomain.com/$1 [L,R=301]

vs

RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} !newdomain.com$ [NC]
RewriteRule ^(.*)$ http://newdomain.com/$1 [R=301,L]

?

Answer 1

No there is no difference in 2 rules.

Order of various flags in RewriteRule doesn't matter.
