yl-2117 divider can be used as a combiner too?

hello,
could this divider http://www.ebay.com/itm/KDI-Power-Di...item5adf8e1fee be used as a combiner too?
The ports are marked in-out-out, but can it be used the other way round to combine power?

Yes, this is a passive power divider, and you can use it to combine the two input powers into the single output.
