Hi, Yes, the recovery is attempted in the same way.
In fact, the second sentence:
Also, notifies a restart in the Updates flow for a DISTINCT Item, such that some Updates may be missing or duplicated.
refers to DISTINCT mode in general, regardless of the unfiltered flag.

For unfiltered subscriptions the first sentence also holds, which covers the case in which either client slowness or network problems or a bandwidth setting causes the Server not to send updates in time and causes the internal buffer to fill. This is not notified for subscriptions that allow filtering.
