Assuming we are talking about PIC plus here...
Once you enroll your external timeshare week into the PIC program, and pay the program fee, those "Points towards VIP status" are there, forever, whether or not you actually deposit your week into RCI each year.
You still own and have full use of your external timeshare each year. You just have to make the decision each year whether to actually use your week, or to deposit your week into RCI. If you deposit your week, you cannot then use your week. But once deposited into RCI, and once Wyndham does their thing, that week is converted into Wyndham points you can use for bookings inside of Club Wyndham.
But you can't do both... and you have to deposit the week 9 or more months in advance of the fixed week to get credit/convert to Wyndham points.
You have to do this every year. But regardless, the "points toward VIP status" remain every year regardless... whether or not you use your week, or deposit into RCI
