No. The key point is that *either* .bash_profile (for login shells) *or* .bashrc (other shells) is run, not both. See the INVOCATION section of "man bash". Typically you would set things that are inherited by subshells (e.g. environment variables) in .bash_profile, and things that need to be set up in each shell (e.g. aliases) in .bashrc.
