Is Hiveon pool really a PPS+ payout method ?

Hi Bitcointalk community,

For starter I am a beginner in this cryptocurrency mining world so pardon my ignorance.

I started to mine on Hiveon pool last week and I was researching about their payout method (PPS+).

On the website poolin.com it's stated this concerning PPS+ :

"PPS+ is a combination of two modes PPS and PPLNS, that is, the block reward is settled according to the PPS mode and the mining service charge/transaction fee is settled according to the PPLNS mode. "

And in the book "Cryptocurrency mining for dummies" it's written this:

"The PPLNS structure pays out rewards proportionally looking at the last number (N) of shares contributed."

Because Hiveon pool is using PPS+ payment method, I ask them this question:

What is the last number (N) of shares applied for transaction fee payout ?

They answered me:

"No transaction fees for payments."

When I tried to clarify my question they answered that they don't understand what I mean.

Maybe someone in this sub-forum here can help me to understand better the Hiveon payout method ?

Thank you
