This is interesting question and the answer is no. It will open the new trade in the current pair, beccause the value of Symbol is empty value (meaning the current symbol). But it's possible to open it on the same pair of the closed trade if we just use the symbol name of the closed trade.
Unfortunately the input field of Symbol is a simple input field, not one of those "Custom" fields where you can choose from many available options. But here are 2 methods you can try:
Write this:
"" + OrderSymbol() + ""
here:

Or put the symbol name into a variable:

Also test whether this works or not, I didn't tested it in real world.
