Good question and I apologize for the omission.

In all the cases, the fences were cedar or PT pickets, 6' tall with
negligible gaps between the pickets.

Still to many potential variables to answer specifically. One would
guess as another wrote that the metal posts were set in concrete while
the wood weren't and/or were deeper. Another question would be was the
failure mode turnover of the post or did they break off? Age and amount
of rain/water would also be effect as would, potentially, the wind
direction and effective shielding perhaps of one side of the cleared
area vs the other such that despite proximity actual wind loadings
weren't the same...far too many possibilities yet to draw definitive
conclusions.
