Only the result of the concatenation matters, not how the original two strings piece together.
Thanks. Unfortunately, none of the UVM documentation, including user guide or reference manual, care to explain this fact.
In fact I spent days understanding the importance of context & instance and got a good understanding only after going through the following tutorial:

In fact there are some many scenarios and pitalls while using config_db and most of the documents make customary explanation and move on.
