The fusible plugs are placed on the rims, near the brake assembly in order to react to heat generated from the brake pack. If the heat in the tyre is not generated from the brake pack (i.e. it is generated in the tyre itself during long taxi operation for instance) then the fusible plugs more often than not won't operate (as rubber is a poor conductor of heat, sufficient heat doesn't reach the plug) and the tyre will burst.
I've never heard of a fuse plug meting due to taxiing or anything tire related.
