Why would I use begin-of-line-invis. over end-of-line-vis or vice versa?

[James Lowe]

Hello,

see the following simple example.

--

\version "2.13.37"

\relative c'' {
   c1
   \once \override Score.RehearsalMark #'break-visibility = 
#begin-of-line-invisible
   \once \override Score.RehearsalMark #'self-alignment-X = #RIGHT
   \mark "Here is some text"
   \break
   c1
}


\relative c'' {
   c1
   \once \override Score.RehearsalMark #'break-visibility = 
#end-of-line-visible
   \once \override Score.RehearsalMark #'self-alignment-X = #RIGHT
   \mark "Here is some text"
   \break
   c1
}

They both produce identical output.

However is there a technical case where I would prefer to use the 
'begin-of-line-invisible' over 'end-of-line-visible'?

Or this just personal preference?

Regards and thanks as always for your time.
