Very Suspicious Price Games in New Development Condos

The Viridian 110 Green Street, Greenpoint Brooklyn (A Magic Johnson Condo) 05/03/2008 Unit A602 listed $529,000 06/02/2008 Unit A603 listed $699,000 07/08/2008 Unit A603 sold for $529,000 07/08/2008 Unit A603 re-listed for $529,000 a decrease of $170,000, -24% Both units at 694 sq ft 1Br 1Ba Does this fall under the heading of "false and misleading prices/sales practices". Was A603 listed at an artificially high price so it could be re-listed at a big discount, which would be caught by search engines? This smells like a pump and dump scheme. Does anyone have any information on the legality of this?
