I practice Archery IRL, but I can only speculate as to the purpose of those things.
The legs decoration may serve a purpose of immediately helping the archer know when they are holding the bow right-side-up. Ironic that they'd use upside-down legs to do that. Another possibility is that the decoration is a balancing weight. Weights are often used on bows, but they are usually attached to the front of the bow, not on one of the limbs /shrug.
The decoration looks solid and heavy. If I were using that bow, and an enemy got close to me (which usually needs to be avoided) I might swing my bow at them making sure that stupid decoration smacked them in the face. Cuz, that would hurt!
