Thanks for sending this. I think your diagnosis is correct, but the solution causes other problems. I think that now if you use EvaluateAnonymousSnippet multiple times, you'll actually get the first one evaluated every time. The very idea behind the Snippet variants was that it can be used outside of cachable paths. It is supposed to return a new thing each time.

So to fix this I would go a slightly different route. (a) Figure out why returning different root nodes causes issues in the first place. Intuitively it should be slower, but still work. (b) Change the API of the linter to take the filenames and use importAST instead of hacking around the snippets (this is a breaking change, but it's still ok for the linter).
