Combining Editions

[Kanwaljit]

So, goodreads librarian manual says this on combining editions:

Editions/translations of the book in other languages. Even though many translations differ significantly, we've made the decision to combine them all, and have people note the differences in their reviews.

There are these two books - The Watchmaker, Saintly Sinner (Pavitra Paapi). These are translation of same book into english, but by two different authors at different times. I am a new librarian, and my question is, does these qualify to be combined? or we can only combine translations with the original work?
Please advice.

I think combining would be appropriate in this case.

Thanks for confirmation Vicky.
