NEON: Cortex A7 is 4 times slower than Cortex A8 ?

I'm seeing Cortex-A7 cycle-timing table here :

http://hardwarebug.org/2014/05/15/cortex-a7-instruction-cycle-timings/

For example, 

VADD.F32 Dd, Dn, Dm takes 2 cycles

VADD.F32 Qd, Qn, Qm takes 4 cycles

same goes for VMUL..

Is this really the case ? I think to remember that both take 1 cycle on Cortex-A8 ?

I'm wondering what's the benefit to use NEON in this case, except for compatibility reason maybe, where some parts could run 4 times faster on some other NEON implementations ?
