No! They just received your passport, than forward it to vfs islamabad, than they will forward to ircc Islamabad office where passport got stamped, after ircc process it will send back to ircc Islamabad office, after that they will send back to that vfs office where the submission was made only if choose to self pick up from vfs, you can also choose one way courier service (fees 6800 pkr), if you choose this service at time of submission than vfs Islamabad send your passport directly at your given address.
My timeline line is

Same day they sent it to islamabad,
Vfs islamabad received it on 22 march,

Irc process my passport on 27 march and send back to vfs islamabad on same day, vfs islamabad received the package and transferred it to vfs lahore office,
On 28th march i got tge email that my passport is ready for collection.
Hope this will help you
