No, it would be additive - you can mount different subsystems on
separate hierarchies. So if you had X divisions for memory, Y
divisions for CPU and Z divisions for suspend-blocking (where Z=2,
probably?) you could mount three separate hierarchies and have X+Y+Z
complexity, not X*Y*Z.

(Not that I have a strong opinion on whether cgroups is an appropriate
mechanism for solving this problem - just that the problem you forsee
shouldn't occur in practice).
