Quick setters and getters question

Hattu

Can someone explain what this underlined part means in practice? I think I understand it but I'm not 100% sure.

This is how i understand it:
You have a variable a=5 with a getter get_a. Regardless of where you call x=a, the get_a will be called too.
So if you want to avoid calling the getter you need the variable b.
When you call b = a, get_a will be called. But if you afterwards use b, it won't call get_a, because you already transferred the value.

I think this example illustrates what the documentation is saying:

# For accessing speed directly, without using a setter or getter.
var speed: int

# For accessing speed using a setter and getter that clamp the value.
var speed_clamped: int:
    get:   
        return clampi(speed, 0, 100)
    set(x):
        speed = clampi(x, 0, 100)

speed = 50 # sets speed to 50
print(speed) # prints 50
print(speed_clamped) # prints 50

speed = 200 # sets speed to 200
print(speed) # prints 200
print(speed_clamped) # prints 100

speed_clamped = 200 # sets speed to 100
print(speed) # prints 100
print(speed_clamped) # prints 100
