the current workspace, MATLAB issues a warning and changes the value of that
variable and its scope to match the global variable.

That does not explicitly describe what happens when the global variable is
being defined for the first time. It seems open to interpretation whether the
global variable gets the value of the existing variable, or whether the
variable should be changed to inherit the default value of the global, i.e.
[].

If this is actual intentional behavior in Matlab, it would be nice to find a
reference saying that this can be relied on. Otherwise it's best to avoid
writing code that does this.
