Katello/Capsule installer/remove locations

Folks,

What's the logic behind where the katello-installer, katello-remove,
capsule-installer, and capsule-remove files are located?

[root@satellite ~]# which katello-installer
/usr/sbin/katello-installer
[root@satellite ~]# which katello-remove
/usr/bin/katello-remove
[root@capsule ~]# which capsule-installer
/usr/sbin/capsule-installer
[root@capsule ~]# which capsule-remove
/usr/sbin/capsule-remove

doesn't seem to be consistent with regards /usr/bin vs /usr/sbin. Is there
a reason?

Cheers
