ONCE AGAIN: Derivatives Whitney - Equity vs floating swap

The more times I look on this TT the more problems I have.

Q4. is a fixed - floating swap. Because we value the swap on a payment date (it’s quarterly and we are 90 days after the initiation) the floating leg payment is $1.

Q6. is an equity - floating LIBOR swap. We are still on a payment date (on the same day 90 days after initiation) and the floating leg is calculated as the PV of the LIBOR rate relevant for that quarter.

How is this???
