I heard an entirely different answer on sci.stat.math,

"If the alternative hypothesis is two-sided; that is, H1: siga N.E. sigb,
then you can reject Ho if F is either too small or too large. You just
compare your F statistic with the .025 and the .975 quantiles of the F
distribution with the degrees of freedom you mentioned.

Jack"

It seems to contradict your claims?
