"You can choose to share one subnet across multiple workspaces or both subnets across workspaces."
as well as:
"You can reuse existing security groups rather than create new ones."
and on
this page:
"If you plan to share a VPC and subnets across multiple workspaces, be sure to size your VPC and subnets to be large enough to scale with usage. You cannot reuse a network configuration object across workspaces."
"you cannot reuse subnets or security groups between workspaces".
Which one is correct?
