 Assuming i have no documentation on this subject, what i posted came from browsing the Net as, being interesting material, i feel enticed to also learn out of such research.
I have found so far that this terminology also existed in France. You can draw from the inventory of a French castle, in a letter addressed to the King, dated December 1213, the mentioning of two foot crossbows (arbalete a deux poids) and also arbalists (arbalete a tour)

Also if you can deal with the french language, you can read the following perspective of a member posting in a French archery forum, in that he assumes that the two foot crossbow is a device from the 10th 11th century.
je peux me tromper  mais  ,d'après moi  l'arbalète à deux pieds  est une des premières arbalètes  10 ième   11ième  siècle.l'armenent se fait  dos d'arc au sol les 2 pieds le long de l'arbrier  et on tire à la main sur la corde
