As far as I can tell, it isn't that user's fault. cPanel put some httpd.conf directives out of order, and so the first VirtualHost (that user's) started loading for everyone. At this point everything looks to be working...
Piotr: 64.62.211.131 is not (nor has it ever been) ns1.heliohost.org. 131 maps to Johnny, whereas 132-134 map to Cody (132 is Cody, 133 is ns1, and 134 is ns2). You're right in saying that 132-134 are all mapping to the same nameserver, but 131 doesn't (nor should it) map to a nameserver. You can do reverse DNS queries (dig -x) on any of these IPs to confirm.
