That was a common spec for cables in manholes so a failure with one cable did not migrate to the other cables. I never installed it on low voltage cables, but for critical systems, I can see it being specified. The cables I used it on were 5kV in manholes and the complete cable in the manhole between the raceway entries had to be wrapped.
Look at Scotch 77
XHHW is the cable type I specify for all wet location wiring and for all wiring between a VFD and the motor.

Yes. Commonly used on medium-voltage cables in manholes to avoid common-mode failures.
