I've watched every episode of Baywatch many, many times, but I don't remember having ever noticed this before. During the final scene of an episode that I just watched, there was a man wearing a Survivor T-shirt that looked to be from around the 1993 or 1994 time period.
Obviously there is the Jimi Jamison/Baywatch connection. But that shirt was from the time period when Dave Bickler had rejoined Survivor in the early 1990's. So I assume that it was mainly the fact that Scotti Brothers were the distributors of Baywatch, and they also released the Baywatch music CD.
