No. The pipe (OR) means it can match cert.cruk.org.something or privkey.cruk.org.something. Because of the parentheses around it, it can be used later on in the replacement, this is called backreferencing. And because it's the first match, it will normally be referenced in the replacement string by '\1'. However, because you need a number directly after that, this would mean '\13` - which is interpreted as the 13th match and will fail. We therefore have to use a numbered group to reference it, which is the '\g<1>'. The second pair of parentheses also has an OR, meaning that the extension can either be 'key.pem', or just 'crt'. Your example doesn't require using that in the replacement later on, so there is no '\2' or anything.
