I think what it means is that it’s expressing the concern for civilians without expressing support for a particular side or claiming that one side is more/less correct or deserves to exist.

It doesn’t mean they don’t have a side or don’t think that one side is clearly in the wrong and there are pretty obvious geopolitical reasons for why these things are happening. It’s just a good strategy optics-wise to make broad humanitarian appeals instead of voicing something more specific, it’s a good way to make the opposition look bad.
