Fiber: 10Gg/s vs 40Gg/s vs 100G/s over strands of fiber over om4

I'm looking up the different speeds that om4 can support and it says that it can do 10, 40, and 100 G/s, ok that makes sense.

I look into what it takes to do 40G/s over om4 and it appears I need eight strands of fiber. It seems like they're bonding the pairs four for send, four for receive. Ok, that makes sense to me.

Then for 100 G/s, you need 12 strands, six send, six for receive. Ok, that makes sense to me.

What doesn't make sense to me, is that om4 can support 100 G/s, but a disclaimer of * Yeah, but with 12 strands.

Isn't that kinda like saying Cat5e can support 10G/s, but with 12 copper wires?

It seems kind of misleading, or am I missing something?
