Meade's horse, like many of the other statues, is in a natural pose, a steady forward stride. The code claims that all four hoves on the platform mean Meade lived through battle, and did not suffer any wounds.
Meade survived the Battle of Gettysburg without a scratch. That, like the other statues, is not the whole story. Meade was wounded in three places during the Battle of Glendale and suffered another wound in the thigh at Antietam. Furthermore, Meade died from complications of these wounds in combination with pneumonia.
The horse code stands as far as Gettysburg is concerned, but this means another officer who's "purple hearts" are not represented in his statue's pose because of that one detail.
