The writing styles seem sufficiently different to me. Also the accounts were both made years ago and years apart.

A much more likely and charitable interpretation of events is that 'lemming year' is an event that many people have experienced and the experience is sufficiently similar that you get accounts that sound the same.

I mean, if multiple people described christmas morning to me, my first thought wouldn't be that they're all in actuality the same person.
