Code execution order

Hello everyone!
I bought PICO-8 some time ago but only recently decided to actually learn it.

One (of many) thing that got me a little confused is the order and speed execution.

The code below shows the text on screen:

function _update()
    cls()
    print("hello",64,64,11)
end

However, if I change the code as bellow, the text does not show anymore:

function _update()
    print("hello",64,64,11)
    cls()
end

What I got from this is: on the second code, since the last command being processed is the cls(), then the screen ends up 'blank'.

But what makes me confused is that I thought since pico-8 runs on an endless loop the cls() and print() will always be called one after another, so I don't understand why in one order the print() is the 'final' and in the other, the cls() is.

Can anyone help me understand this better?
I couldn't find anything that explained this behavior (maube because it's too basic, but since I'm new to this it doesn't make sense to me).
