Does using Azure Service Bus filters on a Subscription incur the cost of an operation?

If a single Azure Service Bus Topic with 10 subscriptions exists. I put a Message on the Topic and it goes to all 10 subscriptions. From the docs I assume this incurs the cost of 10 operations.

https://azure.microsoft.com/en-gb/pricing/details/service-bus

However if we added a filter to all 10 to only allow certain Messages, would it still incur the cost of one operation regardless, i.e to process the filter even if the Message does not go on the Subscription?

Yes even if we are using filters on a subscription and if we receive message from a topic, i.e., message retrieval after abandon, deferral or dead lettering will be counted as independent operations and will considered as billable operations.

So, it will incur an operational charge assuming all messages are delivered to all subscriptions.
