Every time a grid function is synchronised, this is most likely done because boundary points are undefined. Synchronising along doesn't fill outer boundaries and symmetry boundaries, and thus the Cactus boundary conditions should be applied at this time as well.

Even if no Cactus outer boundary conditions are desired, then the symmetry/inter-patch boundary conditions are still needed.

This needs to happen for every grid function, for every sync, not just once per time step for the evolved variables. (And if the evolved variables never need synchronisation, they most likely also never need boundary conditions applied.)
