That's actually for the number of sends, which is separate from the number of 
slots. The number of sends is how many effects a source can have applied, and 
the slots is the number of different simultaneous effects. For example, you 
can have two distinct reverbs (2 slots), but a given source may only be able 
to use one of them (1 send) while another source can use the other.
