amdemod error when fs is twice fc

So I'm running the amdemod command:

demod_signal = amdemod(mod_signal,10^6,2*10^6);

and when I execute it, it gives me the following error:

Error using amdemod (line 43)
Fs must be at least 2*Fc.

I click on the linked 'line 43' text and it takes me to the source code of the amdemod function and I see the following:

% check that Fs must be greater than 2*Fc
if(Fs<=2*Fc)
    error(message('comm:amdemod:FsReal2'));
end

So fs must be at least twice fc but the 'if' clause in the code makes it so that fs must be at least twice fc + 1. Shouldn't the 'if' condition be:

if(Fs<2*Fc)
...
end

Thank you
