condor_submit_dag does not check for cycles, but dagman itself does. after
submitting and running part of the dag you showed, you would eventually
see this in the .dagman.out file:
ERROR: a cycle exists in the DAG
if you want dagman to check the entire dag for cycles *before* attempting
to execute any of it, set:
DAGMAN_STARTUP_CYCLE_DETECT = TRUE
in your condor_config file.
it would optimal if condor_submit_dag did the checking, but it doesn't really
parse the dag file itself, as it's just a convenient way of invoking the real
dagman as a condor job.
