I recall a CASA spokesman making comment that they are a little concerned with the "pay for your own training" and get your endo wherever thing, they did not mention Tiger specifically though. Although quite legal I think it looks a bit GA ish'.
Normally an airline would employ the odd pilot with an "off the shelf" endo but not the bulk of their pilots, and then they would be given extra sim and line flying to adapt to co procedures.

Edit: I understand its not new,
VB, JQ and many others have done it years ago. Perhaps they are picking that point because its something Tiger do differently.
