How to use Traffic Light LED in MicroPython

5:51 I have a doubt.

The Code is :-

while True:
for x in range(3):
led[x].on()
sleep(0.3)
led[x].off()

This should go on like this:-

all 3 led turned on at once, wait 300 milliseconds and all led turned of at once :- repeated process

But why is it going like this :-
r led on, r led off, , y led on, y led off, , g led on, g led off ?
