When processing the input data using the Simple VSR matcher algorithm, there may be more iterations than the number of input records because a merged record may be created on each iteration and added to the queue.
When using the Simple VSR matcher algorithm, the record from the queue is only compared with the value of the master record.
When using the T-Swoosh algorithm, the record from the queue is compared with both the value of the master record and the value of each of the records used to build this master record.
In the example taken from The T-Swoosh algorithm, on iteration 5, the record "John Doe, John B. Doe" is compared with the record "John B. Doe". There is a match if at least one of the three strings "John Doe, John B. Doe", "John Doe", "John B. Doe" matches with the string "Johnnie B. Doe".
