1) It's quite likely she was talking about Ozpin when she said that.

2) Difference between "can come back from the dead" and "can revive people who were reduced to ashes that then scattered in the wind about a whole year ago".

There just isn't anything to revive. She has no body, only ashes, that blew off in the wind, many months before Vol.5 even begins. Even if they could revive her if they had a pile of ashes, finding said ashes is quite literally an impossible mission.

Their only option is to use Magic, and honestly, why would they revive her? Ozpin's own magic is "low", and I doubt reviving a person from scratch would be cheap. And if they used the Relics, it would be (or should be) to defeat Salem before anything else.

And that's assuming that the "revival" would even go well. They could end up messing something up.
