i think i remember this as well. also IMO pre workout carbs are very important. as a matter of fact IMO they are more beneficial than PWO carbs especially as it relates to cutting. i ran a good alternate day fasting diet where the only carbs i ate were pre workout. i was able to cut into single digit bf (sub 10%) from 13% in 8 weeks with no loss in LBM and actually gained some strength if memory serves correctly.
now im not saying IF cant be done without pre workout carbs, im just saying IMO ur training is not gonna be as productive. if u have carbs already present in ur system, then u will also have circulating insulin and fuel to start the recovery process immediately PWO, not to mention the energy from dietary carbs in the form of blood glucose..
just my opinion..
