The fact does not contradict to the variational principle in DMRG. The bond energy except at the center of the system is higher than the true energy per site, thus the variational principle is not violated.

The convergence in variational state is much slower than the convergence in local energy. See M. Andersson, M. Boman and S. Östlund: Condens. Matter/9810093.
