Slightly different. Example if the service only has 2 users:

I listen to artist A's song 1 time, you listen to artist B's song 9 times. We listen to no other songs for the month.

With pooling, A gets 10% of the money, B get's 10% of the money.

With their suggestion, they each get 50%

I actually had to explain this to people that listen to my music. I get ~$0 per month from Spotify and when I told this to one of my friends (who listens to my music) they were like: "But I pay $10 a month!".

Then I had to explain that all the subscribers on the whole platform get pooled together.
