mupad command calling from matlab produce wrong results

I need to evaluate mupad command "discont" from MATLAB. In Mupad notebook the result is correct and looks like:

But, when I use the feval command from MATLAB I get the wrong result

syms x
f = 1/(log(x) + 1)
feval(symengine,'discont',f,x)

ans =

[ exp(-1), 0]

or evalin command

evalin(symengine,'discont(1/(log(x) + 1),x)')

ans =

[ exp(-1), 0]

I cannot reproduce this. In any case, you cannot work with intervals in MATLAB; this is why

poles(f)

gives you just the endpoint of the branch cut of log.
