Welcome to the Quest Study Group.
According to the creator of the deck, the swords will be interpreted as follows:
1) Both swords pointing upwards - YES
2) Both swords pointing downwards - NO
3) One pointing Up & the other pointing Down - Maybe
4) Both pointing towards Right - The answer lies in Future
5) Both pointing towards Left - The answer lies in the Past.
The following thread links all the discussions relating to the Quest Tarot deck.
In one of the discussions linked in this thread, people have already discussed about this yes/no & other features. I don't remember exactly which thread it is, but it is linked in this thread. You can go through these threads whenever you find time. In some of the discussions, you will find even Joseph Martin(the creator of the deck) giving his views/opinions about the deck.
