multi NIC vMotion vs active/active adapters

hi,

we have added two NICs for one switch and created two portgroups for two vmtions. 

vmotion1 uses vmnic0 as active/vmnic1 as standby

vmotion2 uses vmnic1 as active/ vmnic0 as standby

so It is multi NIc vmotion. so during vmotion it uses to NICs and thus increase in performance. faster vmotion.

what if we added only one vmotion and added vmnic0/vmnic1 as active/active adapters. will it use two nics for vmotion traffic?. since both are active active adapters. will the vmotion traffic pass from two NICs? and using default load balancing policies. we have around 8 NICs and no iscsi storage.
