I would not recommend to use particle は twice like in those sentences. My japanese teacher told me this can come as a grammar mistake if used wrong, so its better to use を instead, 私はパンをあまらり食べません sounds better and is more common.
は can be used when contrasting two things, and as a replacement for を in a negative sentence. It does not mean there are multiple topics in a sentence - I don’t think that’s ever grammatical.
If the sentences weren’t paired with anything for contrast, this is just an example of using は instead of を in a negative clause. It sounds more natural than を.

Yeah, I've noticed that this two は particles are only used in negative examples. In positive ones, they used は が を etc. 🤔
I recommend this explanation as a decent starting place about the は vs the が particle for a brief overview. It is a little difficult to explain briefly, since there is no direct English equivalent. https://guidetojapanese.org/learn/difference-between-wa-and-ga/
