I am looking at someones code, and they set local variable X to the
nodeset of LV current-op.

Then they do all their XPATH on $X/some/xpath/statement

I never even thought about the current-op value. Not sure why you would
use it.

The only thing I can think of is that someone who did not yet understand
where the current context is set for XPATH in IDM, so by doing it this
way, XPATH from the document root works.

I usually use XPATH of . to get the current op, if I wanted to say,
bundle it as a payload in an error message or the like.

Never thought of using this variable. Is there some other cost/benefit
I should watch out for?
