The name S.H.I.E.L.D wasn't supposed to be decided at the time of this movie!!!

Rating: 6/10 (10 March 2019)

The short name S.H.I.E.L.D wasn't known untill the very end of Ironman 2 movie, which was many years after this movie,. It used to be "Strategic Homeland Intervention Enforcement and Logistics Division" and Stark & Pepper made fun of the long name and the agent said that they were working on the name.
Am I right??
How this was missed !!!!!?
