The command you just executed.

Or we can use `split-window' here.

Yes.  There are 2 reasons to use `C-x 2' here:

1. It is usually too long to display two command names in the echo area;
(I even want to drop the " since 24.4".)

2. It is more convenient for users to execute the command, since they
won't need to use `describe-function' if they don't know the key
sequence for the command.

We can use `substitute-command-keys' for this feature.

Sounds fine to me.
