I'll see if he responds but I don't think that is what he meant, I think he meant that if the outside temp was 95 it might be 87 in the garage. The other option is because of the heat radiated by the door from the sun the outside temp could be 95, the garage could be higher without the insulation.

My house has light colored "silver" shingles, the garage faces due east and gets no shade. The white garage door would get over 110 degrees and the ceiling would be 98 deg. and you could feel the heat radiating on the top of your head. I had 8 inches of insulation blown in above my attic and added a Styrofoam garage door insulation kit. This dropped the temperature to 6-8 degrees below the outside ambient temperature during the afternoon and evening.

We’ve also thought about adding insulation above the garage to help. I’ve seen the thermal roof barrier too. Does that “cook” the roof shingles by redirecting the heat back into the shingles?
I bought a portable AC for our garage. I connect the end of the vent hose to the rectangular garage door vent when using the AC unit. I can easily remove the vent hose when I'm done using the AC in the garage. Within 15 minutes of running the portable AC the garage is pleasant. I supplement the cooling with a garage ceiling fan and oscillating floor fan. This is the unit I bought: Amazon.com

If you don’t insulate the space above the garage or the lanai you run the risk of problems with the “ceiling “ above the lanai and above the garage sagging. It is well worth the few dollars.

I also found the insulation on the garage doors made a BIG difference. Our garage faces East!

The Solar Guys put a solar attic fan in 2 years ago. Not sure if there are actual savings but figured moving a little air up there couldn’t hurt. The installation went well. I asked them about garage door insulation and since we only get sun in the early morning they said it would be a waste. They also have a garage fan but it just dumps the air into the attic. If it went out the roof I would consider having it installed but for now I am not doing anything.

Add a screen door to your garage. It will stay cool and have air flow. I also put a small fan in the window. Works great
Can you provide information on the screen door for the garage? What is the cost? What is the name of the company that installs the garage door screen?

Having install garage doors over 20 years this is what I tell people. If you face the sun it will help some but is really only useful if you are cooling garage.

Beware that powered fans on the roof might not do what you think. The air will short path, meaning new air comes in the other top roof open vents and exits via the powered fan. Air remaining in the attic stagnates and gets even hotter.
Adding ceiling insulation is much more effective.
