What the code was meant to do, written into the code itself as a docstring

Returns the most syntactically similar word in the collection to the specified word.

The change

99 for item in collection:
1010 similarity = bigram_similarity(word, item)
1111
12- # The similarity must be above the threshold and if this is true for
13- # multiple words, we take the most similar one
14- if similarity > max(max_similarity, threshold):
12+ # The similarity must meet or exceed the threshold and if this is true
13+ # for multiple words, we take the most similar one
14+ if similarity >= threshold and similarity > max_similarity:
1515 match = item
1616 max_similarity = similarity
1717

The check that tells the two apart

fail→pass·tests/test_text_processing_helpers.py::TestFindSimilarWord::test_exact_threshold_is_accepted

Check file tests/test_text_processing_helpers.py, taken without changes from the fix and copied onto the older code, so the exact same check runs against both versions.
