It definitely does.

When working with pros who worked with other coaches, I can argue the other coaches' viewpoints better than they themselves can. So when I explain them the alternate logical route, they get a better picture as to why my pefered system is more effective and efficient.

I think it helps build trust with the athlete too, when instead of shitting on the alternative, you show them you really understand it deeply, but just see to many flaws in it.
