Yes, this is not deterministic though - some places have duplicates,
some don't

Yes, there are separate overlays for each duplication, for example:

 From 7070 to 7070
  before-string        [Show]
  eglot--inlay-hint    t
  eglot--overlay       t
 From 7070 to 7070
  before-string        [Show]
  eglot--inlay-hint    t
  eglot--overlay       t
