By going to finer resolutions, you are testing convergence of a problem rather than addressing the question of whether or not rupture propagates on to the branch.  Branch fault may or may not rupture depending on factors like rupture speed, branch angle and stress orientation but should be independent of resolution as long as cohesive zone is well resolved.

TPV14 and TPV15 3D benchmarks were designed in such a way that branch fault ruptures completely in TPV15 entire branch fault rutpures while in TPV14 rupture does initiate on the branch but isn't able to propagate to the other end of branch fault.  
(I can send you figures of rutpure time contours for each of these cases in case you don't have access to SCEC dynamic rutpure code validation website)
