What is Scotch Doubles please?

On the events listing for the South East Asian Games in December one of the cuesports is 'English Billiards Scotch Doubles'. I've seen an 8 ball pool game that was alternating shot and I think was Scotch Doubles? Anyone confirm that? And is that what in being played in the SEA Games, or (more likely) is there a billiards version of the same? (I'd guess no reason billiards can't be played that way and presumably is)

Scotch doubles is a alternate shot format where you take one shot, your partner takes the next and so on.

I believe true scotch doubles involves a mixed team of female and male players but ATM it's considered any two person team alternating shots.

Thanks for confirming that - still surprised to see both a competition for 'English Billiards Doubles' and 'English Billiards Scotch Doubles' in this. No Women's competitions for either billiards or snooker (despite 7 medal competitions), just 9 and 10 ball pool for the Women, which I think's a shame ...
