Addressing Starting Pressure vs. Coverage Area?

Can anyone make sense of extended coverage sprinkler max spacing and areas to me?

Looking at NFPA 13 (2016) Table 8.8.2.1.2 or (2022) Table 11.2.2.1.2 "Protection Areas and Maximum Spacing (Extended Coverage Upright and Pendent Spray Sprinklers): In unobstructed and obstructed noncombustible construction, the max spacing is uniform for 196 square foot protection areas as 14 feet. Kinda makes sense, 14 x 14 is 196.

But then when we get to 144 square foot spacing for Ordinary Hazard, we have 12'-0" maximum spacing (okay, 12 x 12 is 144); but then when we do 144 square foot protection area for extra hazard or high piled storage on this chart, you can have 15'-0" max spacing.

The way I'm reading it is: If you have 12' x 12' spacing in ordinary hazard, you can use the Extended coverage pressure for 144 square feet but if you have 10' x 14' spacing, despite a smaller protection area in ordinary hazard (144 sqft vs 140 sqft) because of the 14'-0" spacing, I should calculate using the head's starting pressure for 196 square foot area of protection starting pressure.

Whereas the same situation in extra hazard or high piled storage would allow me to use the 144 square foot starting pressure, as I haven't exceeded the 15'-0" maximum spacing or the 144 sqft area of protection.

Just seems counter-intuitive to me. Can anyone make this make sense?
