Yes, you are correct. ODB may be good, but it is not magic.

In fact, in the documentation of on_delete (Section 14.4.15)
there is a warning exactly to this effect. It starts like
this:"

"Note that this is a database-level functionality and care
 must be taken in order not to end up with inconsistent object
 states in the application's memory and database. [...]"
