This was using the \intertext command, not two seperate math mode environments.

It seems this \intertext command is not properly handled in LyX. I had
the same problem, when you press 'space' it jumps you out of the
command. You may want to file this as a bug or feature enhancement.
I'm not sure which it would be.
You may be stuck to ERT for this true AMS functionality.
