The Breath of Evil mind space doesn’t make sense?

Ok so, just read book 15 and the mindspace doesn’t make sense.

So when Pineapple gets taken over by the other mind, he immediately get transported to the mindspace, but there are thousands of silkwings and hivewings taken over by the othermind, so why can’t they come into the mindpspace?

And sure, you can argue that Lizard/Freedom has to let them in first, but Moon came into the mindpsace and Lizard/Freedom was like: How are you HERE? So.. it doesn’t make much sense to me.

Explanations?
