Are/were the items tracked by Stock By Attributes?
FWIW, just ran a purchase through a system setup with the current version of SBA available through http://github.com/potteryhouse for ZC 1.5.4, added two different SBA tracked items, then while on the shopping cart, modified the quantity of the first added item to zero (without selecting the delete button), the item was removed from the cart, progressed to checkout, email received about the order only reflected the one item that was last in the cart.

So would say, although it is good to know that custmers are only being charged for what they have indicated they wanted in to purchase, the system response is abnormal and something is causing it. Although perhaps not currently a significant issue, it should be resolved else things may get complicated if another issue arises...
