I don't know the answer to that question, but you can avoid this if you
do a DNS lookup to see if nameservers for the zone exist in the
appropriate TLD registry, instead of a WHOIS lookup.

It's free, much faster, and doesn't suffer from this problem. It's fairly
accurate (a little less accurate than WHOIS because it finds
expired-but-not-yet-deleted domains as available, but WHOIS can be wrong,
too. In any case, I assume you're telling people something like "these
related domains might be available, click here to check...").
