Yes. As you said it gives confusion while entering on R/As, especially to those who have been driving on light-free signals as in UAE. But you will get used to this in due course of time as I did in 2 months. My suggestion is that once the yellow light starts blinking simultaneously if there is a digital counter counting backwards to 'zero', it would be very helpful for drivers, as he could know when exactly will the "dangerous" RED be 'ON'
