This is pure conjecture, but my guess is that the film of fabric softener left on the clothes would interfere with the fire retardant fibers/may be flammable itself.
From my understanding, the old fire gear I wore as a much younger man, the fabric was treated with special chemicals that could be washed out if not laundered correctly.
