If I know I have just a use left in a tome or sword and I have the breathing room, I use it up and grab it.
People are used to planning around plasma balls, fireballs, and Levin shenanigans. They are not used to the books and sword coming at you at wtf mph.
Besides, if you have the choice of knowingly getting your item back and getting the respawn clock started at your choosing, or hoping, not knowing, you'll hit with that last use, and then restart the clock when you've possibly put yourself in a precarious predicament, I'd pick the former option and have the threat of the book or sword for those few seconds.
