I've got the same on my laptop with Radeon 7500, so I guess this is generic Xorg issue. It turns out that this issue is related to the way the virtual screen are handled in Xorg. If you want to change something only on one output, you need your change to fit into the Screen current virtual size. When you don't specify the output, it looks like the change is done at a higher level where the virtual can be updated. I suggest trying this Xorg configuration to get the command 2 to work. Note that command 1 and 2 are no equivalent. Also, command 2 is generally use in the context of multi-head operation.
