since the reporting sharehloder sold as a reporting SH then he must report the sale.
That being said if howeevr the SH has 9% and sells 6% he really only need to report up to the point where he holds 4.9999% any sales after that are no longer reportable provided they were not executed simultaneously with the stock sold when teh SH held >5%

So if he 9% and sells 5% in a single block then he reports the wholesale but if he sells 4.1% and then teh next day sells anpther .9% ofnly teh first sale is reportable,
