I would hazard a guess that this is true.
Line changes at Pinnacle occur because the numbers are getting bet.
At Rio, I suspect that, for games that they aren't getting much action on, they just middle the Don Best screen. If you happen to try to snag a good number before they have a chance to move it, you'll get about a 10-second pause (where your confirmation screen is in limbo), and a "Line Changed" notice at the end.
