It would be useful to know why this works for future ref...

The double quotes are OK but not necessary - smarty/PHP is very forgiving about converting between strings and numbers. $products is an array containing all of the products in the cart. The {section} {/section} loop repeats whats inbetween them changing $product each time to point to the next product within $products. Outside of the {section} {/section} loop the value of $product isn't defined so your test of $products[product].productid won't work. You could have moved it inside the {section}{/section} but then it would include the file once for each product that isn't 3491 in the cart - not what you want. There is no simple function to just ask if productid 3491 exists in the $products array so you have to loop through the array and check every item in the cart. Hence the need for the assign within the {section}{/section} loop to set a flag if product 3491 is found.
