No. As it's possible to drop more thatn one item at a time onto a
droplet, the variable 'these_items' receives a *list* of aliases. If only
one item is dropped, the list contains only one alias, but it's still a
list and so can be counted.

'Choose folder' returns just an alias (not in a list). As an alias
doesn't have any countable elements, it can't be counted.
I'm not sure what you want to happen after that. If you want the folder
to be handled by process_folder(), the easiest thing would be to replace
the entire snippet with:
set this_item to choose folder
process_folder(this_item)
... or:
process_folder(choose folder)
