There are generally two type of heat in this scenario sensible and latent.
Think about when you heat up water on the stove. If you were to graph the temperature T against the heat energy added Q, you would see the temperature gradually rise as the amount of heat was added. This is the 'sensible' heat. But at a certain point the water would hit boiling temperature. You're still adding heat but the temperature is no longer increasing so what gives? The energy is now going towards phase changing the water from a liquid to a gas. This is the 'latent' heat.
The OP is just saying there are more paths than just latent heat transfer, which is why they said you won't overheat in Antarctica if it's 100% RH. Your statement here is that evaporative (latent) cooling won't happen at 100% humidity but sensible cooling can still occur. You're both on the same page.
You are saying the same thing as the OP.
