This can’t have been the reason. \once makes the tweak valid for only 
one point of time, after which it will be immediately reverted.
Additionally, there’s \undo which can be used as a shortcut for the 
corresponding \revert. So these examples both work as expected (at 
least, here they do):

\version "2.19.16"
m = \relative c' { \tuplet 3/2 { c8 c c } c4 }
{
  \m
  \once\hide TupletNumber \m
  \m
  \hide TupletNumber \m \m
  \undo\hide TupletNumber \m
}
