They show how to install what the manufacturer calls apron strips on page 13 of these install directions.

That would make it look a bit more finished I guess. It just looks like tile attached to tile in the OPs case to my eye. If that wall was flat drywall and with glass doors that are frameless the look would work. If the doors have some kind of an end frame I would think you would want one tile to end under the frame and the other start.
Thanks for posting the install link.
