YES!!! That has been my experience too... some of my friends
have been complaining about this also. In fact sometimes for some
inexplicable reason, its New Trip when i board a bus immediately
after alighting from my previous bus, though its only the 2nd
trip.
And very often when i try tapping my ezlink at the machine when i
want to alight, it just says EXIT OK, without beeping or saying the
fare and value left. I wonder has the fare balance been refunded to
the card or eaten up by SBST? 
Anyone has similar experiences?
