VM snapshot - space consumption location

Hi,

If I create a datastore of 2TB and create a VM with a thin provisioned disk of 1.5TB, then lets say I create a snapshot and leave the VM running on the snapshot for a while.

Will the VM space consumption (now including the snapshot) still be restricted to 1.5TB? Meaning the datastore can never run out of space in this scenario with a VM on a snapshot?

I know that keeping the snapshot for more than 72 hours is not recommended but want to understand what is the space limit of a snapshot (VM vdisk vs VMFS datastore)

Thanks
