There may have been the international market to cater for as well as video releases to consider.
I don't know how other countries broadcast them back then but I know that in the UK Sky showed one series at a time, so they might have not got onto Season 2 of DS9 until after season 7 of TNG had finished its run. That would have resulted in potentially a six month wait for the second part of the two-parter to air, or even seeing episode 2 before episode 1. That did happen in fact with the Bones/Sleepy Hollow crossover I was talking about earlier. The Universal Channel aired Sleepy Hollow first (episode 2) so we couldn't watch that episode until Sky started broadcasting Bones weeks later.
Plus a two part episode in the video tape era would have meant that to see both episodes of the crossover, you'd have had to have bought two VHS tapes, including one tape from a series you may not watch.
Box sets today have got a bit more freedom so they could at least include the other episode as an extra feature if they wanted to.
