[Bio-software] Multiple hits in blast reports

[Maurizio A. Strangio]

Recently I used NCBI blastp with an AA sequence; the resulting report contained multiple hits in the description field separated by ">" with  those hits clearly shown in the alignments section:

>gi|1... <description>     
gi|2...  <description>
gi|3...  <description>

followed by alignments involving the query sequence and the HSPs related only with the first hit (gi|1...).
What are gi|2, gi|3? 
I thought they were hits with the same evalue and score of the first hit  gi|1. However, it doesn't seem so since looking at the hit list you can find hits with the same evalue and score appearing on different lines.   
Thanks for any help.
