I thought they sounded pretty confident on "sameness" - whether that is their version of sameness or the FDA version remains to be seen. But personally I'm a little more cautious after their call.
Craig wheeler was somewhat confident as well with the following statement during his prepared remarks
We believe our competitors will need to do substantial work to meet the FDA's criteria for approval.
So the question remains whether Teva has already completed the "substantial" work required or whether it has some ways to go. Evidence appears to point to the latter but as you wrote Teva's bullishness can't be taken lightly IMO.
