Verbal communication is a different skill apart from engineering and written communication.
People have to plan how to break subjects down before and during speaking. Not everyone has adequate practice.
Some people have trouble with eye contact and might be fighting subconscious social anxiety while simultaneously scrambling to put their thoughts into words. If an audience wasn't present, it would be easier for them.
Some truly brilliant engineers struggle with this.
Edit: If you don't intuit this or perhaps struggle, I strongly recommend taking an improv class. It should be a fun and safe environment where you'll experience your brain lighting up all the communication pathways at once. If you want to go more subtle and read people's body language and tone, take a Meisner class. These both help tremendously for people that don't get in the daily "exercise" as a part of their normal day to day. I've also heard good things about Toastmasters.
