You will still negotiate a new PPP Session, It is not possible to lose Sync
and keep PPP alive, Technically, Virtually or Magically.

Keeping the same IP, Yes this can happen.

oh, and as for the ppp session losing sync - to be more accurate, the
adsl sync/lock is very slow, so the rp-ppp session times out and then
goes for a full reconnect with a resultant discconect.  If the
interuption is short, rp-ppp doesnt see the loss and its transparent to
users.  With iinet, it used to get a new IP number when it happened,
though I think they have have fixed that and it tends to reuse the IP
