Makes sense, fructose + glucose replenishes glycogen faster than glucose alone in a glycogen deplete state. This is presuming A your muscle is insulin sensitive so the sugar doesn't metabolize into liver fat and B your body is actually glycogen deplete.

"Abstract: Carbohydrate availability in the form of muscle and liver glycogen is an important
determinant of performance during prolonged bouts of moderate- to high-intensity exercise.
Therefore, when effective endurance performance is an objective on multiple occasions within
a 24-h period, the restoration of endogenous glycogen stores is the principal factor determining
recovery. This review considers the role of glucose–fructose co-ingestion on liver and muscle
glycogen repletion following prolonged exercise. Glucose and fructose are primarily absorbed
by different intestinal transport proteins; by combining the ingestion of glucose with fructose, both
transport pathways are utilised, which increases the total capacity for carbohydrate absorption.
Moreover, the addition of glucose to fructose ingestion facilitates intestinal fructose absorption via
a currently unidentified mechanism. The co-ingestion of glucose and fructose therefore provides
faster rates of carbohydrate absorption than the sum of glucose and fructose absorption rates
alone. Similar metabolic effects can be achieved via the ingestion of sucrose (a disaccharide of
glucose and fructose) because intestinal absorption is unlikely to be limited by sucrose hydrolysis.
Carbohydrate ingestion at a rate of 1.2 g carbohydrate per kg body mass per hour appears to
maximise post-exercise muscle glycogen repletion rates.
Providing these carbohydrates in the form
of glucose–fructose (sucrose) mixtures does not further enhance muscle glycogen repletion rates
over glucose (polymer) ingestion alone. In contrast, liver glycogen repletion rates are approximately
doubled with ingestion of glucose–fructose (sucrose) mixtures over isocaloric ingestion of glucose
(polymers) alone. Furthermore, glucose plus fructose (sucrose) ingestion alleviates gastrointestinal
distress when the ingestion rate approaches or exceeds the capacity for intestinal glucose absorption
(~1.2 g/min). Accordingly, when rapid recovery of endogenous glycogen stores is a priority, ingesting
glucose–fructose mixtures (or sucrose) at a rate of 1.2 gkg body mass1h1 can enhance glycogen
repletion rates whilst also minimising gastrointestinal distress."
