Yes, you're right. It will be fixed in next release. You also could fix it in your JComments template by editing files:
/components/com_jcomments/tpl/default/tpl_email.php
/components/com_jcomments/tpl/default/tpl_email_administrator.php
/components/com_jcomments/tpl/default/tpl_email_report.php
And replace code:
<?php echo $comment->name; ?>
with
<?php echo $comment->author; ?>
Thank you for your bug report!
