Bowtie behavior with --best

[analyst]

ok, i apologize it may be just something very obvious but despite reading manual several times, i can not understand the following behavior. A sequence searched against build in e_coli index:

Q.1 what happened to other 4 alignments with best (no quality is considered as you see)
Q.2 Where is the alignment 4760194 coming from when --best is used

Thanks for your response
