The more likely scenario is that the poster accidentally mentioned you at first and then edited their post to correct the mention.

Inaccurate mentions on forum
@JeffreyWay , logged in for a moment to sneak in a series when I saw I had a notification that I was mentioned. In the forum. So I went to the post becasue I couldn't remember contributing to that thread, and as it turns out I hadn't someone named @ rony had (one letter off).
Any chance you have Algolia or some fuzzy search running in the background to check mentions? For that specific use case I'd use exact match.
Have a great day.
