Why doesn't decreased insulin secretion during stress cause problems?

During fight-or-flight situations, alpha 2 receptors ( which are inhibitory receptors ) of the pancreatic beta cells are stimulated, and as a result there's decreased insulin production. While it benefits the body by producing increased blood sugar level, I don't understand why Insulin doesn't cause some problems. Such as, since insulin increases glucose intake by the muscle tissues ( skeletal muscles are supposed to be used more in flight-or-fight situations ) and increases glycolysis ( which produces energy ), wouldn't decreased insulin release during flight-or-fight situations cause less glucose intake and less glycolysis ( as a result less energy production ) by the muscle tissues? And wouldn't less energy produced by the muscle tissues cause them work less efficiently?
