The problem was more that the only ships with Sea Wolf - which was the only thing we had at the time that COULD have taken out the exocets - were guarding the carrier group during the loss of Sheffield.
AFTER the loss of sheffield, the policy was changed such that each class 42 was escorted by a class 22 (with sea wolfs).
The Argentian navy did hit Glamorgan with an exocet after that, but Glamorgan wasn't anywhere near anything with Sea Wolf defenses at the time.
The 'friendly' aspect is likely apocryphal, and possibly based on the fact that the Glamorgan and Antrim were both exocet missile destroyers themselves, and might thus have had issues with targetting a missile of the same type. But since neither of them had any point-defence systems it was moot.
edit: or it may be from the fact that Broadsword's sea wolf system 'locked up' during the sinking of Coventry, and was unable to attack the inbound A4s that bombed Coventry. But from what I can see, the prevailing belief was that it was unable to lock on for the same reason Sea Dart on Coventry wouldn't - it couldn't discriminate the A4s from the land behind them.
