In a video posted on England's official channels, the Three Lions were taking part in the rondo routine perfected by the likes of Barcelona and Ajax.
Both Jack Grealish and Nick Pope were in the middle and had to try and nick the ball off the larger group of players including Henderson and Maguire as they kept possession in the small square.
The drill is predominantly played in tight spaces and using just a single touch to keep the ball moving along.
Henderson was doing the counting as the likes of Harry Kane, Jude Bellingham, Tyrone Mings and Kyle Walker-Peters played one-touch football at a fast pace.
But then after the 43rd pass, Maguire, for reasons unknown, decided to stop the ball when Pope came over to press him.
He took two touches and none of them were a pass, the momentum of the drill killed by Maguire coming to a halt.
And that left Henderson perplexed and annoyed in equal measure. Stood next to him, he stared at Maguire in disbelief and also appeared to say, "What you doing?" to his England colleague.
The clip has gone viral on social media and garnered reaction aplenty from fans:
Henderson played the full 90 minutes as England came from behind to beat Switzerland with goals from Luke Shaw and Harry Kane.
Maguire, meanwhile, was an unused substitute for the game at Wembley.
England host Ivory Coast in their second friendly of the international break on Tuesday before club football resumes.
