The timer will refresh/reset as long as traffic is coming in. I'll have to check as it may not refresh immediately. We had a recent issue where we monitored this for traffic in a 'match across services' configuration and I found that the record refreshed about every 30 seconds as long as traffic was active.

 

So as long as the device is receiving traffic for a configured virtual that matches the record, the record will stay 'fresh'. I'll have to follow up or hopefully someone else can chime in and clarify if persistence records are periodically refreshed or continually refreshed. I know at least in one case ('match across services') the records were refreshed every ~30 seconds.
