Description
Required for JDK-8044406, but not any more because refinement and card scanning during garbage collection do not interfere any more with each other.

This has probably been obsolete (at least) since JDK-8213108 where (former) Update RS phase has been redistributed into Merge RS/Scan RS phases; further, since JDK-8276098 (this is a much later change than the other), the BOT is never updated by refinement/Update RS (or the "equivalent" Merge RS), but directly during garbage collection.
