[Cogito]

The streamlines don't need to meet for Bernoulli to apply.

That statement, that the upper airstream flows faster because it has to meet up with the lower airstream, is wrong and easy to disprove experimentally.

So, putting aside that specific statement, re-read the post you're replying to.

The airstream above the aerofoil does travel faster, and there is a lower pressure region there (commensurate with the effect described by Bernoulli), and it turns out that this is a valid way to model the forces involved just as it is valid to model them as a redirection of the airstream.
