What you say is correct. I have used SRAM Force group since early April. If it is setup correctly, this won't happen.

I have stated this in previous posts. Because there is only one "paddle" for shifting, user error will happen (perhaps more often than Shimano/Campy). It isn't idiot proof (speaking from personal experience).

Also, with just one paddle, when installing the brifters and connecting to the derailleurs, it can be tricky to get the brifters to the right starting point (i.e. when they should be for the easier associated cog/chainring).
