I doubt that they will update the list, because the listed replacement may still be available from somewhere, and this helps if you are servicing and need to replace/swap a item.
I see the 4000 and 4900 both uses UHF, the same as my 2000.
My 2000 remote was a 1.0, while the 4000 and 4900 uses a 1.5; but the 1.5 UHF replaces all 3, but has extra buttons that don't do anything.
The 6.2 UHF PRO and 6.3 UHF PRO remotes can control the 2000, 4000, and 4900 from SAT Mode when the Black Tab inscribed with UHF is installed.
If you have a 6.2 or 6.3 available, you can easily test it either by programming the AUX Mode button with 3 and the correct address; or with the SAT Mode button by pulling off the (Blue) Tab and then slide the white plastic switch to position 4.
EDIT: If you have a 6.3 UHF PRO Remote Kit, here's a list of the switch positions and Key Tabs used.
Position 1 = TV2 UHF PRO (Selected with Blue Tab, Black 2)
Position 2 = TV1 IR (Selected with Green Tab, Engraved 1)
Position 3 = TV1 UHF PRO (Selected with Green Tab, Black 1, Engraved UHF PRO)
Position 4 = UHF (Selected with Black Tab, Engraved UHF)
