It is correct. Mach 3 macro refresh rate is 10Hz. If you need to detect an input pulse less than 100ms, then it cannot be guaranteed that a macro will detect the change, which is why you had to use PLC for many commercial tool changers.
However, as I'm sure you're well aware, when you call G-code from a macro, that is then handled by the main motion engine, so is not restricted by the 10Hz refresh rate. The macro simply stalls until the motion is complete.
