Why does the regular expression work "in reverse"?

Question

Ruby on Rails

There is a regular expression: https://regex101.com/r/ZLTSoK/4
Which for some reason unknown to me does not work in Ruby:

re = /(.*?)(?:\(|\/)(?:.*?)\n/
line = re.match(tmp) if re.match(tmp).present?
puts line

tmpis the string to be parsed.
At the output, I get not "some text" or "even some text", but the exact opposite - what is in brackets, a slash, an ellipsis.
What could be the problem?
