GetAllBidders does not return the Bid History like the site

GetAllBidders is designed to return a unique list of bidders so as to enable the seller to make Second Chance offer listings. It does not return the bid history like the site does. For instance if the site returns the history as below:

User ID	Bid Amount	Date of bid
dts1	US $5.50	Jul-31-06 11:23:06 PDT
dts2 ( 1 )	US $5.00	Jul-31-06 11:22:40 PDT
dts1	US $4.00	Jul-31-06 11:22:31 PDT
dts2 ( 1 )	US $3.00	Jul-31-06 11:22:17 PDT
dts1	US $2.00	Jul-31-06 11:20:49 PDT

GetAllBidders will return only two offers in the BidArray corresponding to the highest bids placed by each of the users.

Here is the GetAllBidders request:
