dt (s) specifies the interval, in seconds, at which this VI is called. If dt (s) is less than or equal to zero, this VI uses an internal timer with a one millisecond resolution. The default is –1.

... nothing in there about automatic delta time calculation. |
The second sentence of the documentation you quoted states that it uses a timer to calculate delta t, which sounds like "automatic delta time calculation" to me.
Because the VI's default for dt is -1, the default behavior is for it to calculate its own dt internally based on the timer. When you wire something real up to it, that will disable the timer and use that value instead.
