This follows the new/old formula for continuous shows at WDW. The intent is to very publicly advertise how long there is until the next showtime outside the theater, to encourage people to meander outside (ideally in gift shops and the like) until a few min before showtimes. All of the new Epcot shows (even Canada, but we'll come back to that) have adopted this model, just like Country bear and Tiki Had the whole time. Recently Pixar Film Festival adjusted its exterior wait time clock to mimic this as well. Personally, I'm somewhat surprised that LMRA and OMD never got them, although they both pose their own challenges, which brings me back to Canada. A lot of these B/C Tickets Films are stuffed in the back of a pavilion of area, where there should be an E-Ticket, or at least something with a weenie. In fact, I'd be willing to blame the lack of a weenie signaling the presence of a theater or anything important in the back of Canada for its lower viewership. Canada was the first to install (although IIRC that stalled out on activating it) a clock off the promenade of World Showcase to advertise the countdown. Unfortunately, it somewhat discourages wandering in the pavilion, but it also incentivizes more people to go back by knowing there is a show there. Depending on how it does, I wouldn't be surprised to see venues like LMRA adopt this.There’s a sign out front that says “_ minutes until next show” so I imagine you’re meant to wait until the next performance starts.
