Mauersegler;
Thank you for your post and response.
The engines will have separated from the wings right at impact and will have tumbled ahead because of their weight and the momentum they had at impact which was around 80kts or so.
Engine compressor rotation will have had little to nothing to do with where the engines ended up.

Your expressed caution in re assumptions made about the condition of N2 and turbines based upon the condition of the N1 after an accident, is well said - I heartily agree.
