No that's incorrect.
Low carbs in fact will give someone physiological insulin resistance which is not a bad thing, just means the body is functioning correctly.
As far as your GNG statement (decades old myth) that's way wrong.
GLUCONEOGENESIS is always happening and is a demand driven process not supply.
Regarding excess protein -> glucose
The Ketogenic Diet for Health: If You Eat Excess Protein, Does It Turn Into Excess Glucose?
The body mostly turns protein into glucose based on need:

It is hard to eat enough excess protein to remove you from ketosis entirely, often it doesn't change anything:

And of course, the genius, Peter, says the same, aminos CAN provide oxalaoacetate to reduce ketogenesis, but the question is, does this happen in the liver?
Hyperlipid: Ketosis and Protein
I happily accept any other articles that state the contrary of what is being proposed here. However, the evidence and biochemistry stands to reason: it is quite difficult to over consume protein to the point of being out of ketosis.

The Myth of 1 g/lb: Optimal Protein Intake for Bodybuilders
Finally...The human evidence on reasonable variations in protein consumption disagree. The rate of GNG is relatively fixed and is NOT affected by supply!
There is not a single study in humans (and none in rats/frogs/pigs/et that I'm aware of) which indicate too much protein does anything but spike blood glucose moderately. The only study I've seen that tested both insulin and glucagon indicates that the I/G ratio is preserved, meaning the BG spike does not "kick you out of ketosis."
I did 5 days of very high protein 450+ grams..a lot higher than I normally do some meals were over 100 grams of protein per meal, whey protein, & I did blood ketone tests over 50 times in those 5 days and never did I have any problems with ketosis. bg spiked a little but dropped shortly after and often below pre-protein ingesting numbers.
in a ketogenic individual, the evidence of raising insulin is that, while true (though the insulin spike is generally mild and short-term) there is a near immediate glucagon spike, which preserves the insulin/glucagon ratio.
So eat all the protein you want...
