I just improved an edit from the suggested edits queue and I am trying to work out if I did the right thing.

The original question is by a new user with 1 reputation. It was closed by Rubik's for lacking a system/edition. The edit added a lot of good information and clarified the question, however it was done by another new user with 1 reputation. (Now 3 by the approved edit).

To me it seems clear that the edit was made by the OP and they have accidentally made multiple accounts. (I left a comment to let them know). My reasoning is that the edit clearly contains information that is was impossible to know without being the OP.

I know by approved/improving the edit I was in a grey area but I choose to do it in the name of newby friendliness since it wouldn't be easy to explain to them why the edits were rejected without causing frustration.

However, I am also concerns that I may have inadvertently approved the high-jacking of a user's first question and causing the negative first impression that was the very thing I was trying to avoid.

What should I have done here?
