Hi, couple questions before I buy Honorbuddy. What do "sessions" mean?

So I'm planning on buying the basic honorbuddy which sells for ?24.99 (~$30 USD).

It says it's a 1 year subscription but it also says 1 session? What does this mean?
For the RAF subscription, it says 5 session. If someone can please let me know what this means thanks.

 

1 session = 1 bot at a time

5 sessions = 5 HB's running on up to 5 bots at the same time.

 

Ahh I see.

Since I only have 1 account and dont plan on multi boxing this doesn't concern me.

Thanks for the help!

 

then you will only need 1 session.
