Using the 'present continuous + always' usually indicates an annoying habit.
In your example the speaker probably does not like her 'helping the poor'. The problem here is that perhaps we might not see 'helping the poor' as something negative or annoying, if we are altruistic.
However, consider the following examples of more explicit annoying habits:
I don't agree that always + present continuous is limited to annoying actions. It certainly CAN be used that way, but my instinct is not that the speaker wants to convey annoyance - tone of voice would tell me that. In writing, I find it neutral.
Nona is such a kind person. She's always out there, helping the less fortunate.
As Magda's question asks what this sentence would imply... What would you suggest?
Using GG's inclusion of the aspect of intonation, which is very important if this sentence were to be spoken, it could imply many things... including 'gratitude'... depending on how it was said...
Given that no particular intonation was specified, I would suggest that the sentence implies frequent and continual involvement in projects aimed at helping the poor.
