The Soyuz LOK spacecraft for lunar orbit flights had a back-up engine positioned at the front of its orbital module. This back-up engine was to be used to break the Soyuz out of lunar orbit in case the primary engine in the instrument module failed.

But as I recall, the earth orbital Soyuz carried both its primary engine and back-up engine in the instrument module.

Why did the LOK have its back-up engine on the orbital module? Does this presume that the instrument module only had a primary engine and no back-up engine?

The premise is wrong. It did not have a backup engine in that location. That was the Kontact system.
