Yeah I meant more that it's harder to maintain the weapon juggling every round. If you throw a weapon, it's not available to throw again the next round. In melee, you are starting the round with a different weapon, so your mastery combo is reversed. Even if you can use your object interaction to stow your weapon and draw your original weapon, you can't do anything with your original weapon after you have attacked. If you have 3 attacks, you can stow the weapon at the end of your turn, but then you have no weapon equipped for your reaction.
With thrown weapons you risk being left unarmed but because throwing them is free (as opposed to dropping or stowing) you can always equip another weapon at the end of your turn as your free interaction.
