Right, trying to call comments_template inside the shortcode just
isn't going to work.

Instead, why not have the comments shortcode set a global variable,
then base your call to comments_template later in the code based on
that global variable. Like this:

function sword_comment_shortcode($sword_comment_atts) {
global $sword_do_comments;
$sword_do_comments = true;
}
add_shortcode('comments-shareit', 'sword_comment_shortcode');

... later ...

if ($sword_do_comments) {
 comments_template();
}
