Search fails when two NEAR operators are used, and second proximity is less than the first

[regstuff]

Describe the bug
Consider the sentence: word2 something something word1 something word2 something word3
A search such as word1 NEAR/2 word2 NEAR/2 word3 will result in a match with the sentence
Similarly, word1 NEAR/3 word2 NEAR/3 word3 will also result in a match
word1 NEAR/3 word2 NEAR/2 word3 should also match this sentence but it does not.

A sentence without the first word2, such as: something something word1 something word2 something word3
will work for all the above proximity searches.

Search fails when two conditions are met:

1. Wherever there are two (and possibly more) NEAR operators, if the proximity distance of the second operator is less than the distance of the first
2. There are two instances of one of the words (word2) that satisfies the first proximity rule, but only one instance of the other word (word3).

MRE
Below python code creates the sentence and runs the 3 searches mentioned above. First search fails where as the rest work.

row = {'title': '<p>word2 something something word1 something word2 something word3</p>', 'contentid': '1'}  
resp = indexApi.insert({"index" : "products", "doc" : row})  
print(resp)  

resp = utilsApi.sql(f"""SELECT * FROM products WHERE MATCH('word1 NEAR/3 word2 NEAR/2 word3')""")  
print(resp)  

resp = utilsApi.sql(f"""SELECT * FROM products WHERE MATCH('word1 NEAR/2 word2 NEAR/2 word3')""")  
print(resp)  

resp = utilsApi.sql(f"""SELECT * FROM products WHERE MATCH('word1 NEAR/2 word2 NEAR/3 word3')""")  
print(resp)
