i would have thought they would only put out ac current after they sense one that matches g99. 
When the grid goes off, if there are two on the same phase, i cannot see how they know it is off unless the other inverter (be it battery or solar fed) happens to go off…
It would be useful to examine the test condition and the result for one of those “reputable manufacturers“…

They've been extensively tested by folks like the German and Swiss test labs, people who don't mess about or take backhanders.

They will not put out AC current if they don't detect a suitable grid voltage and waveform. If they do detect one then they follow it and the try and perturb it a microscopic amount now and then.

If you are backfeeding with only another grid following inverter then a) the whole waveform will collapse in a mess anyway in moments, and b) the disturbance will ensure it happens and is seen, whereas poking the grid won't.

Now if you build yourself a suicide cable to a generator and have a strong enough grid forming generator they will be fooled. This is actually used (without the suicide cable) by Sunsynk/Deye and later Tesla kit to back microinverters when the grid proper is down. In those cases the inverter grid forms on the microinverter port and the microinverter power goes into the batteries and they are either managed by feeding them 52Hz when you want to shut them up or just disconnecting them like a generator when the battery can no longer reliably take the power they are supplying.
