Current and upcoming experiments should improve the sensitivity to e(alpha) -> e(beta)gamma decays by an order of magnitude. This paper assumes that one of the tau -> e(beta)gamma. decays is observed, and explores the structure and consequences of the required new flavoured couplings. In simple models (a low-scale seesaw, leptoquarks) it is shown that the dipole vertex function is proportional to a product of flavoured matrices from the Lagrangian (a Jarlskog-like invariant), provided that the loop particles are weakly coupled to the Higgs. Secondly, if the dipole vertex function has a hierarchical structure, this might imply that only some of the tau -> e(beta)gamma modes can be observed, due to the approximate zero implied by the bound on mu -> e gamma. The assumptions underlying this potential test of a hierarchical structure are discussed.
