Oddity in the Alexander signal

[Viridiana]

So, when Wedge was calling out dis and dahs, I rather figured it was Morse Code. Well, the four letters he gives us first are:

“Di dah, di dah di di...
Di, dah di di dah...”
What in the blazes...?

Or, in dots and dashes, *- *-** * -**-

This spells out ALEX, almost certainly short for Alexander. The thing is, once you get the decoder, we hear the following plaintext:

“Today's schedule for Gordias. Registration at seventh bell. Stop. Louse the coeurl cubs at third bell. Stop. Rest and recuperation at second bell. Repeat. Today's schedule for Gordias...”

Which, clearly, doesn't mention Alexander at all. Anyone have any ideas as to why the Morse and plaintext would differ so?
