I was thinking about this a little after I sent it. I think this would be equivalent to soft sync only if the slave oscillator's reset threshold is beyond what the integrator can reach by itself. So there would have to be an offset added so that the oscillator won't oscillate without the sync signal. I think that's still not exactly the same, but maybe close enough.
