He is not confused. I think.
The bacula should not to recycle a volume, even if there is not appendable volumes.
The manual says: "The Volume Retention record defines the length of time that Bacula will
guarantee that the Volume is not reused counting from the time the last
job stored on the Volume terminated". Not mention to jobs on catalog.
The files and job retention period comes to prevent catalog growing, not to recycle volumes, says the manual.
The Volume Retention record defines the length of time that Bacula will
guarantee that the Volume is not reused counting from the time the last
job stored on the Volume terminated. A key point is that this time
period is not even considered as long at the Volume remains appendable.
The Volume Retention period count down begins only when the Append
status has been changed to some othe status (Full, Used, Purged, ...).
When this time period expires, and if AutoPrune is set to yes, and a new Volume is needed, but no appendable Volume is available,
Bacula will prune (remove) Job records that are older than the specified
Volume Retention period.
The Volume Retention period takes precedence over any Job Retention
period you have specified in the Client resource. It should also be
noted, that the Volume Retention period is obtained by reading the
Catalog Database Media record rather than the Pool resource record.
This means that if you change the VolumeRetention in the Pool resource
record, you must ensure that the corresponding change is made in the
catalog by using the update pool command. Doing so will insure
that any new Volumes will be created with the changed Volume Retention
period. Any existing Volumes will have their own copy of the Volume
Retention period that can only be changed on a Volume by Volume basis
using the update volume command.
When all file catalog entries are removed from the volume, its VolStatus is
set to Purged. The files remain physically on the Volume until the
volume is overwritten.
Retention periods are specified in seconds, minutes, hours, days, weeks,
months, quarters, or years on the record. See the
Configuration chapterTime of this manual for
additional details of time specification.
The default is 1 year.

I think you might be confused about the meaning of the Volume Retention
directive. It controls automatic pruning, but it doesn't prevent recycling if
the volume has no jobs remaining in the catalog. The latter can happen if the
Job Retention directive in the Client(s) caused pruning prior to this backup.
