Don't beat yourself up over this.
For many years, Vehicle Manufacturers were very adamant about changing plugs on aluminum heads when they're
cold.
I believe part of the problem is, if there is any amount of combustion residue ( hard carbon ) on the end of the threads of the plug, you have a tendency to pull the threads out of the head.
A warm/hot engine ( softer threads ) increases this risk.
