Multiple villagers can get on the same bed when you right-click and left-click with a bed.

To reproduce :

• Make it so it's night time
• Take a bed in your inventory and drop it
• Spawn a villager and make it go to the bed
• Right click and left click on the bed
• Spawn a new villager, he'll go into the same bed as the first one resulting in multiple villagers using the same bed
