Why isn’t my chewing to swallowing a fluid motion?

I understand the concepts and being able to chew enough and swallowing properly. But if I practice this how come I can’t chew and then swallow in one fell swoop? If I’m trying to chew and swallow properly there is a gap of 1+ seconds where I ‘prepare’ to swallow, but this feels very unnatural and almost robotic.

if you watch Mike Mews video of the kid eating broccoli you can see this quite obviously, is there some other skill to being able to do it all in one motion? Or am I doing it wrong?
