Why does the bot move the mouse straight up, above the item to be withdrawn, before withdrawing?

 

Example:

 

The bot want to withdraw raw sharks, but first it moves the mouse above the raw sharks, hovering the stews as you can see. This happens every time it's banking and to me it's very bot-like. I am not sure if their anti-bot system can pick this up, but it is repetitive and can larm them, I think...

 

Here's the example of my code:

if(api.getBank().contains(Cooking.food)) {
	if(!api.getInventory().isFull() && !api.getInventory().contains("Raw shark")) {
		if(api.getBank().withdrawAll("Raw shark")) {
			for(int i = 0; i < 100 && !api.getInventory().contains("Raw shark"); i++) {
				API.sleep(API.random(12, 18));
			}
		}
	}
} 

For now I'm not going to be looking at mouse movements, I did a while back and it's really time consuming. At this point I'm only really concerned if something is flat-out failing.
