Ah but you will fall backwards and that would be soo interesting for your partner who would fall forwards :>)

If I as first man spring backwards with my right, instead of left, foot, and my partner springs forward with her right foot, there is a risk that her right foot will land on my left (supporting) foot, which IMO would create more of a risk of a stumble or fall than intersecting jetes. By both dancers starting on their "top" foot, this is avoided.
Plus, I find it very visually appealing to watch four good dancers dance a quick-time pousette in rhythm with their feet mirroring each other.
