In the context of knowledge of something, the phrase "to catch up" is apparently being used in both active and passive ways. For example:
I have to catch up on the latest news.
Can you catch me up on the latest news?
To me, this seems not logical if I think about catching up requiring some effort on the part of the person that is not up to date. Instead, I would prefer
Can you help me catch up on the latest news.
To me, the usage gets more confusing if catching up refers to physical distance, for example, a cyclist who wants to catch up with another. For me,
Rider A was caught up by rider B
would mean that A was in front but than B caught up with him, rather than B helped A catch up with other riders in front.
My question is:
What is the meaning of the cycling example for native speakers?
PS: updated in response to comments. It seems that I was not actually talking about "passive voice". Apologies to @TRomano for the changes after their answer.
