AFL has become a real programming language, not just something to drive charts.

However, if I remember correctly, there were some conditions that required the entire formula (including button-code before the clicked button) to be re-executed when a button was clicked. Else you are looking at a button panel that is only half refreshed after the button clicked. It could take, in your case another second, to refresh all buttons. For example, this would show up if you had many button columns and were collapsing the panel. The panel would collapse in two steps.
