There can be only one active (running) bulk operation per shop (for each app) at any given time

What exactly does this mean? If I write some code to get results using bulk operations ( for collections over 1000 products), based on user input, will this be an issue?

one active (running) bulk operation per shop (for each app) : Does this mean, if there are multiple users using my app, Shopify will still only allow one operation per store? If user 1 triggers a bulk operation on their instance, user 2 will have to wait for user 1’s bulk operation to get done? To see any results on user 2’s instance of the app?
