above is correct

> Configured a manual pool with the above template
> Configure "Initial run" with domain membership and so on
> Assigned permissions to the pool

no, there is a bug in 3.5 regarding manual pools loosing the stateless snapshot on shutdown:
Bug 1239153 - Stateless VM snapshot gets deleted when user shuts down VM in a Manual Pool type
it is fixed for 3.6, we're considering backporting the fix to 3.5.5

in addition, important to understand that if vm is started from admin portal,
regardless to pool-type (auto/manual), it is started as statefull (no snapshot) and any change (including sysprep) is saved.
note also that when starting pool vm from admin, it doesnt assigned with permission to any user..
only when vm started from user portal (or pre-started) it will be stateless, and the user that started the vm will get the permission to this vm.
