What he's talking about is that a resistive load in a coffee pot
doesn't change in resistance by anywhere near 10X over it's operating
range. If they did draw 10X, then the typical 1500W hair dryer
would draw 120amps when first turned on and you'd have tripped
breakers. A lot of this is probably being taken out of context from
the case of light bulbs, which do vary substantially in resistance
from cold to hot. But in this case, cold is room temp or below and
hot is it glowing at thousands of degrees. That doesn't happen in a
coffee pot, where the heating element is only going from 70 deg to
maybe 200 and the resistance change can be ignored.

The element gets much hotter than 200 degrees.
The inrush current depends on the particular element material.
