Can dedicated instances share same hardware within the same account?

I was going through AWS docs for Dedicated Instances and I'm confused by the following statement:

Dedicated Instances might share hardware with other instances from the same AWS account that are not Dedicated Instances.

(I'm assuming hardware here means a physical server)

It explains about sharing the hardware with other non-dedicated instances, but what about sharing the hardware with other dedicated instances within same the account?

Can a hardware be shared by two dedicated instances within the same account?

If not then, wouldn't that be expensive to allocate separate hardware for each dedicated instance request?

Yes, hardware can be shared by multiple Dedicated Instances within the same AWS account.

In AWS, Dedicated Instances run on hardware dedicated to your account, meaning no other AWS customers’ instances will be placed on the same hardware. However, this hardware can be shared by other Dedicated Instances and even non-dedicated instances from your own account.

This design allows AWS to provide isolation at the account level without the high cost of dedicating separate physical servers for each Dedicated Instance.

Here is a reference directly from the AWS documentation on Dedicated Instances: https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/dedicated-instance.html

yes - sharing hardware across your dedicated instances is its main purpose:

Dedicated Instances ... run ... on hardware that's dedicated to a single customer.

In other words, other customers' instances don't run on the same hardware as your dedicated instances.

Reference that you quote is clarification that AWS may run your non-dedicated instances on the same hardware as well
