If you scroll down through the fares list on the QR site linked in the OP it has a number of places listed from there, with NBO the lowest at $585 RT and DXB at $625.
I think they meant HOU generically (IAH specifically), but I tried IAH-NBO-IAH 2/15-2/22 and it came up at $577 RT.
Seems kinda arbitrary that they might put 2 or 3 specific cities on sale per departure city, since everything runs through DOH anyway. Dallas gets Bangkok, Houston gets Nairobi, Atlanta and Philadelphia get Kuala Lumpur, etc.
