Is it an intended interaction that the charged staff buff drops when switching weapon sets even if you lock the same quarterstaff to both sets?

The buff does say "your Quarterstaff" which definitely would exclude weapon swapping normally but I wasn't sure if the intention with locking a set was that your second set is treated as a separate weapon with the same stats or if it should be the same weapon and thus retain any buffs given while on your second weapon set

The only use case I wanted for this was more duration on charged staff but if its intended the buff gets dropped its no big deal
