Can't make the compose() works

To me is impossible to make the composer method work. So I wrote this basic example anda everything works mostly fine for my needs, but the compose don’t. Is There anything wrong with the way I’m using it?

from datetime import timedelta
import srt

td = timedelta(seconds=1)

a = srt.Subtitle(index=1, start=td, end=td, content='Word 1')
b = srt.Subtitle(index=2, start=td, end=td, content='Word 2')

c = [a, b]

print(srt.compose(c))

c = a.to_srt() + b.to_srt()

print("========")
print(c)

print("====")
d = list(srt.parse(c))
print(d)

The creators of this module may want to adjust the docs as the same example is given there. https://srt.readthedocs.io/en/latest/api.html#srt.compose

>>> from datetime import timedelta
>>> td = timedelta(seconds=1)
>>> subs = [
...     Subtitle(index=1, start=td, end=td, content='x'),
...     Subtitle(index=2, start=td, end=td, content='y'),
... ]
>>> compose(subs)  
'1\n00:00:01,000 --> 00:00:01,000\nx\n\n2\n00:00:01,000 --> ...'

The output shown in the docs will not in fact be produced unless reindex=False is passed.

It’s filtered because it’s never displayed (end <= start). If you want to just verbatim print the Subtitle objects, you need to pass reindex=False to srt.compose.
