Using % man cat | less is exactly the same as just using % man less.

I must be missing something here. Could you please explain above. On my (arguably OpenBSD desktop)

% man cat | less

piples man pages for command cat into less thereby allowing regular expression search vi style.
% man less
Just gives me man pages for command less.

You seem to claim that those two are the same. Could you please explain?
