It seems that the comment was introduced when renaming `guessMinLength` to `guessPattern` 11 years ago (symfony@f7200e4#diff-c8f9f12ae6d4b48f0f41c30c0cd9716c41e92563a7ded52264a0eb3540ad04e5).
However the comment seems to be about a min length, as is it brings to value when guessing a pattern IMHO, so let's drop it.
