Weird parenthesis interaction?

[Florin_Florea]

I was trying different functions in the calculator, and i stumbled on some weird ones:

Although they are different, they should have overlapping results, but they dont as shown here:

taking x = 1, for the first function the result is undefined, but it shouldnt. The second function works properly.

Am I missing something? Or is it a bug?
