The cortex-A7's pipeline support dual-issue, so I want to ask what's the dual-issue mean?

I find some answers say that dual-issue means that the cortex-A7 can issue two instructions per clock.

But in the cortex-A7's pipeline diagraph, it has integer, multiply, floating-pointing/NEON, dual issue, load/store.

I also want to ask the dual issue there refers to what? It has what fuction or how it works?
