But are they saying the whole piece came off at once. Traditionally, you get
a void, a bit pops off this creates a tiny vortex which nibbles away along
the exposed edges.

Not piece, pieces. Quite a number of pieces shed from the intertank
structure, as the photos here show:

In some cases it appears the whole shed piece of foam left in pretty
much one chunk, as is visible on the video stills from the camera on the
ET: http://spaceflightnow.com/shuttle/sts127/090715gallery/ (note image
4 and 6)
On images 1, 8, and 9 it appears that some of the debris is transparent.
That could be a video artifact of some kind...or is that sheets of thin ice?
