No, this is the way it went down. We were in front and Miami assigned us 280 or faster (us in a 560, VMO 292) and assigned the Global 280 or slower. Few mins later ATC queried us as to our speed, we said 280. ATC queried the Global's speed, they said 280. Then they asked Center, "Can you slow down that Citation and let us go fast?" At first Center said no, then he changed his mind and said yeah. He gave us lower and we saw them go over us. Approaching FLL, the Global got vectors to join the final with all the airliners, 27R, which slowed them down anyway and we got right in on the shorter runway, 27L. It struck me as an a$$hole move just to eventually slow down for the final anyway, kinda like someone who squeals the tires and floors it at a green light only to catch up with him when he's sitting there at the next red light...what's the point??? If we were enroute at 390 and I was in his way I could totally understand wanting to get around us, but this close to the terminal area? Typical south florida mentality, always in a hurry to get nowhere fast.
Don't even get me started on those Gulfstream pricks...
