If you think about that, it's brilliant. She shows him that the new bearers of the EoH are also capable of imprisoning him in stone should he act up again, so basically saying "shape up or it's permanent this time". Admittedly, it nearly backfired because of Fluttershy, but in the end it all worked out, so I think no harm, no foul.

As for the first time, obviously she felt that she and Luna just wouldn't have what it take to reform Discord; if there hadn't been a Fluttershy in this group, she probably would've never tried to reform him in the first place. Obviously, she felt, if it could be done (him being reformed, I mean), his magic would be good for Equestria to have.
