For choral music it is an old convention to merge dynamics if time of start, 
time of end, and target are all identical.
Have a look at e.g. the 19th century Peters editions of Mendelssohn's SATB divisi 
motets, e.g. this score 
<http://imslp.org/wiki/6_Motets%2C_Op.79_%28Mendelssohn%2C_Felix%29>. The
same convention is used today, see e.g. bar 31, basses, in this score 
<http://www.giamusic.com/pdf_previews/pdfdocument_previewimages/GWOM105_sample.pdf/WOM105%201%20to%2012%20GIA%202013%20%28dragged%29004.png>.

It's also uncommon to use "a2" and "Solo x" in such scores, a2 is assumed or 
rests are used instead.
