It most certainly does.
If you take binary data and encode it as base64, it doesn't reduce the
entropy, it is just a coding, no data is gained or lost, it is a
reversible operation.
In this case I am doing the same thing, but coding as words. It is fully
reversible, no data is lost or gained.

Passwords don't have to look like random gibberish to have good amounts
