### Abstract

We investigate the low energy dynamics of ${\cal N}=1$ supersymmetric
$SO(N)$ gauge theories with a single symmetric tensor matter field. These
theories exhibit non-trivial matching of global 't Hooft anomalies at the
origin of moduli space. We argue that their quantum moduli spaces possess
distinct Higgs and confining branches which touch at the origin in an
interacting nonabelian Coulomb phase. The matching of anomalies between
microscopic degrees of freedom and colorless moduli therefore appears to be
coincidental. A formal mathematical relation between the $SO(N)$ model and
an analogous $Sp(2N)$ theory with a single antisymmetric matter field provides
an explanation for the anomaly matching coincidence.
