xpcs0_1 and xpcs 1_0 can't be both SGMII

PFE0 is connected to Serdes 1 lane 0 and PFE2 to Serdes 0 lane 1. 
In u-boot/*/serdes_hwconfig.c, there is a combined validation that prevents both pfe0 and pfe2 to be configured in SGMII. 

I don't understand why? Since both are on different Serdes instances what is the problem here? 

I tried to configure both of them in SGMII from m7 cores and I can see the communication on both pfe 0 and 2.
