ReserveTicketsEx Special Requests - issues

Okay, so i got a long weekend of rest and came back to the problem.  Verified that the Hotfix had been applied (it was), (WebAPI_hotfix_2378), and tried again.

I should be able to exec ReserveTicketsEx with the following params:

1. sWebSessionID:
   QI0VS118X92O5HE056X7RPG5WYJ4DTNTKP24H8ND17R91QXSLPBJPJC8Y9VR5491
2. sPriceType:
   17
3. iPerformanceNumber:
   15160
4. iNumberOfSeats:
   4
5. iZone:
   0
6. sSpecialRequests:

   WheelchairSeats=1andContiguousSeats=4andHoldCode=444andLeaveSingleSeats=Y

The best i can conclude is that the functionality is less than i was expecting and understood, but also still not quite right.  

1:  If i only use 1 Special request parameter, HoldCode=444, it works.  and will only give me seats in 444.

2: If i pass in  HoldCode=444andLeaveSingleSeats=Y it gives me seats that aren't in a 444 holdcode!  This basic test is making it virtually unusable.  

Has anyone else experienced this or have they tested it and gotten results otherwise?
