I don’t believe deactivation is part of the user suspension process. In the UI, you would need to press the ‘deactivate’ button separately if you wanted a returning suspended user to also reverify their email.
Deciding if that’s what you want and tackling it as a separate operation may get better results. 
There’s some guidance for bulk suspensions in this topic if that helps Administrative Bulk Operations
Though if you try that and find it’s outdated let them know and they should be able to update the guide accordingly.
