Okay, pilots are so often used unaltered as first episodes (at least these days), most people aren't aware what a pilot actually is. (I hate, hate, hate when the first regular episode of a series has "Pilot" as its title, especially when the rest of the episode titles follow a theme.)
First a network options the rights to a series.
Then it hopefully greenlights a pilot, which is basically one big in-house preview for the higher ups of mostly the first episode and maybe some important later scenes.
Which is then produced, in GoT's case with Ehle as Catelyn and Merchant as Daenerys.
Then the network says what it liked and what it didn't like and hopfeully greenlights a first season.
The changes are then applied and if necessary recasts happen. Then the actual season is produced with, depending on the individual case, the pilot being incorporated either in full, or in parts, or not at all. Not having to reshoot the first episode is obviously cheaper. [Unused pilots are usually buried deep in the network archives and (especially those of series that did manage to go on air) heavily sought after by fans.]
And after all that the network greenlights one or more seasons at a time, but obviously no more pilots are shot. Naturally if a series changes networks, the new one also only greenlights/orders seasons, not pilots.
