Difference between On1 and On2

Recently YQ taught the performance class a 'theory' lesson on musicality and difference between On1 and On2 Salsa. (I should convert the diagram to online... and post here)

One key point which I think is very notable is....

For On1, just before the pauses, both dancers are in 'closed' position (2 feet together)
For On2, before 4 and 8, the dancers are in Open position.

There is a big impact here, in that these pauses are 'photo moments', where people watching the dance get to see a break between flurry of movements.

This is also when On2 dancers like to style A LOT.

e.g. Every Open break, after 6,7... On2 dancers are in an open position, and a very common styling here would be for both dancers to look away and use count 8 to style, and come back to connect on 1.

Similarly, in a CBL, On2 leads like to do it OPEN (i.e. going opposite direction like in an open break) rather than forward (towards the follow), and point away (a styling move) at count 8, then step + lead on count 1 to execute the CBL.
