Does the order of annotations matter - Weird output

[dav009]

I've been playing with scrapely, and this script generates some weird output:

1. annotate url1
2. try scrapping url1, got the expected output
3. annotate url2
4. try scrapping url2, got nothing from scrapping url2.

I thought it could be train since it is not supposed to be reliable, but when exported the annotated data the annotations seems alright.

Then I inverted the order:

1. annotate url2
2. try scrapping url2, got the expected output
3. annotate url1
4. try scrapping url1, got something different from the annotation( a subset of what was annotated)

Is this a expected behaviour ?
