Two quotes from two books, concerning high hands in shorthanded pots

[kitaristi0]

Zee:

"As you can see, the high hand in a short-handed pot tends to do better [than a low hand]."

Cappalletti:

"But at head-to-head, good high card hands are usually an underdog to any random hand with several low cards."

Don't these statement kind of contradict each other? Or is there a distinction to be made between short-handed pots and head-to-head pots?
