Yes, according to the github search documentation, ' and ) are not considered when searching:
You can't use the following wildcard characters as part of
your search query: . , : ; / \ ` ' " = * ! ? # $
& + ^ | ~ < > ( ) { } [ ]
. The search will
simply ignore these symbols
https://help.github.com/en/articles/searching-code
I assume the search sees `(require 'cl)` simply as `require cl` and that can match either cl or cl-lib or other libraries that begin with cl.

And it also takes into account comments and ifs for older Emacsen, which presumably are ok. - Romanos
