Thanks for that clarification, going to update my post to reflect that.

No problem! The Steem Bluepaper describes pretty comprehensively what's up with the bandwidth:

Bandwidth Rate Limiting for Fee-less Operations
Because the witnesses are paid entirely through the generation of new tokens, there is no need
to charge users a fee for powering the blockchain. The only reason to charge a fee would be
as a deterrent to prevent users from completing an unreasonable amount of transactions, which
could potentially impact the performance of the blockchain.
In order to place reasonable limits on the system use, each user is given a limited bandwidth.
Whenever users perform blockchain operations such as token transfers, posting content, and
voting, it uses up a portion of their bandwidth. If a user exceeds their bandwidth allowance, they
must wait to perform additional actions until their bandwidth recharges.
Bandwidth limits adjust based on network use, so users have a higher bandwidth allowance
when the network usage is low. The amount of bandwidth that an account is allowed is directly
proportional to the amount of Steem Power a user has, so users can always increase their
bandwidth allowance by getting additional Steem Power.
