It looks like the cans were shot individually, not as a group. If that is the case, drgss's notes are right on. The perspective is a little off.
The camera is also placed toward the middle or top of each can, which flattens out the top of the cans, and, most importantly, applies a gentle curvature to the bottom of the cans. This is where the problem starts.
When you simply reflect the cans, that bottom curve is reflected as well, and thus creates an incorrect reflection. Currently, your reflection appears like two opposing parentheses )(, whereas the true reflection should appear like two cradling parentheses )). Then, the reflection should continue on from there.
One way to counter this is to shoot with your camera at ground level. This flattens out the base of the object (in this case, the can), and rounds out the top. Then, if you ever need to fake a reflection, you can do it with much more ease.
In this case, you're either going to have to re-render, re-shoot, or do some very clever (and potentially time-consuming) retouching.
