It could be that, but the people that I've seen omit the
'expr' did so because they simply forgot it was required, 
not because they didn't understand when it was needed.

FWIW, the 'expr' conditional really works more like the
'test' or '[' commands in Unix shell environments than
anything else.   

I agree more examples are needed on conditionals, it's
also worth looking at or adding some in the pagelist examples
in the cookbook.
