My understanding is if the brochure or technical specs of a breaker specifically mentioned that it can be reversed feed then it's fine. But if not, then don't. I wonder if there's a more technical explanation on this.
On the other hand, the only other reason I see why the switchgear manufacturer reverse feed this breaker is to shorten the length of the bus bar connection to the main bus.

I do not know this for sure as a rule, it just has been my experience thus far.

My last post should read...
It has been my experience that any molded case breaker with a **non-interchangable** trip unit can be reverse fed.
OUCH! My Apologies...
