action work

Good afternoon. In the business process step: https://onebox.spacehall.com.ua/admin/shop/workflowstatus/534/action/new/ I reserve products and also use the action Change process step when there are enough products in stock with active check-box Switch the process even if at least one of the products of the process is in stock. The idea is to have the process switch to another stage when one of its products is taken out of reserve. But to my surprise, this action works out constantly on the hourly crown. I suppose this is due to the fact that the products are reserved in this particular process and the action, as it were, ignores this reserve?
