Running loop using random match numer in Boundary Extractor will result to same values

### Expected behavior

when defining a random match number in Boundary Extractor each iteration should random a new value

### Actual behavior

when running the script in loops (1 user at a time) the value is always the same

### Steps to reproduce the problem

1. use in scripte a Boundary Extractor with random match number in at least one of the responses
2. run the script with threads (a few users simultaneously) - the random works fine
3. run the script with loops (1 user at a time) - the value is only being randomed once and all requests are always using same value
