Meaning, they changed to the "Rotol" (brand name) airscrews when the "DeHaviland" (brand name) airscrews proved to be a problem. They ditched the airscrews, they don't say in that passage that they reverted from the boost.
There may be documents somewhere that say they did, but so far I haven't seen any quoted text in this thread that says they did.
