IDC error?

" We need Sam Carter" said Rodney, looking rather upset that he actually had to put it that way.

" I'll contact the SGC and ask for her" said Liz Weir

Two days later the gate activated and the IDC was interpreted by the computers to read that "Colonel O'Neill" was inbound.

"Wonder what he did to get demoted…." Said Rodney fading off as Sam slipped through the wormhole, it deactivated, showing that noone else was coming through.

"Carter!..It said O'Neill on the IDC?"

"Yeah that's right, it IS" Smirked she holding up her left hand to show off the rings.
