That's only true in a servo system where the encoders feed back to the computer, and the encoder power is not interrupted by the E-stop. So, the simple Gecko 320 scheme doesn't qualify, for instance. If you power the Geckos off, or if they fault from a sudden stop, then the position reference is lost.
