Traditional humidifier with Boveda for regulation?

[shopkins82]

Shouldn't the Boveda only absorb any moisture ABOVE the rated RH, and release moisture if BELOW the rated RH? Hence acting as a regulator supplementing the main humidification source (even if that source is beads instead of a sponge)? Again, if I doesn't work in practice I wouldn't be overly shocked or surprised, just validating my though process...
