That's just pure stupidity, you're interpretation of the scenario is complete nonsense and shows you have no clue what you're talking about.
Ilia was in his full guard to which Charles locked his arm up and opened guard to look for a submission attempt or a sweep. All Ilia did was step over Charles's right arm for a second, it wasn't even a crucifix position. The moment that happened Charles was already working for a leg submission and he turned that into a submission attempt. Ilia immediately looked to escape which he did and then back out of any grappling.
The scenario clearly shows that Charles is far more advanced in grappling and Ilia would not have much success there.
