I don't think its a bug, it seems to be the intended function.

1) First it checks that we either said 'don't compare the title' or the 
titles match (!compareTitle || Title1 == Title2)

2a) Then it ANDs this with a check that either we said 'don't compare 
the subtitle' (!compareSubtitle) OR the subtitles match (Subtitle1 == 
Subtitle2) AND also we've either said 'only if present' 
(compareSubtitle==2) OR at least one of the sub-titles is non-empty 
(Subtitle1!="")

I just don't know why its a useful function :-)
