BibLaTeX: Some entries show author field as a dash (-) [duplicate]

I am observing a strange effect in BibLaTeX. When I have two papers printed in succession that do have the same author (see example below) I get only a dash (-) in the second reference where the author is supposed to be printed.

What is that and where in the manual can I read more about this (I can personally not imagine why anybody wants such a behaviour)?

I would like that authors are always printed regardless if they where mentioned or listed before before or depending on the environment of the citation...

Here a self-contained example:

\documentclass{article}

% BibLaTeX
\usepackage[
backend=bibtex,
style=authoryear,
firstinits=true,
maxbibnames=99]{biblatex}

\begin{document}

\nocite{Meyer1,Meyer2}

\setlength\bibitemsep{5pt}

\end{document}


And the bib file:

@article{Meyer1,
author = {Meyer, Bob},
title = {{Some Great Paper}},
journal = {Some Great Journal},
volume = {9},
year = {2015},
pages = {99--109},
issue = {9},
doi = {99.9999/99999-999-9999-9},
}

@article{Meyer2,
author = {Meyer, Bob},
title = {{EAnother Great Paper}},
journal = {Another Great Journal},
year = {2015},
volume = {9},
pages = {99-109},
number = {9},
doi = {88.8888/8888888.8888888}
}

• I can perfectly imagine why one may want such a formatting: it's easy to spot at once how many authors are referenced. It is just one of the traditional styles. – Bernard May 8 '15 at 11:13
• Its only working if authors are sorted in direct succession. If the same author appears again further down the list, he or she is printed normal again. So I really don't think its very useful. – RalfB May 8 '15 at 11:42

The solution is loading biblatex with dashed=false
