Thank you for posting the full deck. The conclusion is pretty clearly stated that the engineers thought the shuttle would return safely, even with missing tiles. The focus on this one slide out of context seems totally wrong.
"Contingent on multiple tile loss thermal analysis", i.e. "we're running that model now and until we're done we're not sure, but the tests we did so far suggest that a tile loss should not prevent safe return".
It isn't really that unclear. There are formal words, but - unlike typical managerial presentations - there's also content behind them.
