If it's another personalized coupon, then it becomes up the cashier - although considering only one relates to points, and the other relates to the price - as long as you reach that $5 level you have fulfilled the requirements of the points promo and it should be awarded.
Now, how many will actually become $0.49 is a gamble - there doesn't seem to be any pattern in how they are applied. The best you can do is just try it.
