yes, if that is what the mfg. requires. Beyond a 30 ft run would most likely result in more potential lateral movement ( expansion & contraction) than is normally accommodated by your typical expansion space. don't forget....the expansion and contraction shows up as the cumulative expansion or contraction of all boards.....apparently beyond 30ft your expansion spaces may not be sufficient. The tee molds create a break to accommodate potential movement.
