The comment above it in the file

Only refunds if the reserved-piety var still exists, so two callers cannot refund twice

What it does

• the game's own tooltip text · ◦ our reading of the script line · code the script where neither exists

“They” is whatever it runs on (the scope it is called in). The scripted triggers and effects it calls link to their own pages; $PARAMETERS$ stay as written: each call fills them in.
