The issue you where browsing your bot's "conversations" logs and click on the button to "correct" the bot's response. This enters a new response to the "question" that the bot was asked. In this case the "question" is "hockey", so you are entering a "response" to "hockey".
Your issue is you are trying to enter a "question and response", just enter the "response".
i.e. "I love hockey, it is the best sport."
To create a new question and response click on the "Add New Response" link, or the green + when browsing "new responses". Then paste the pattern into the question field, and the response into the response field.
Please review this how 2 on how to on how to train your bot,
The sample code from the forum post you mentioned was for a "response list" file, that you could import. It was an example of a question and response, not an example of a response.
In general you do not need to use patterns, as just entering "hockey" would match the question "hockey" and other similar questions. You could also add "hockey" as a keyword to the response to match any question with "hockey" in it (that did not have a closer match).
Note that the Pattern("* hockey *") will not match "hockey" as * requires a word, i.e. it would match "do you like hockey eh?".
To match anything with "hockey" as a pattern use Pattern("^ hockey ^"), ^ matches any words or empty space. The pattern rules are from the AIML standard.
I changed your bot's response to use Pattern("^ hockey ^"), and it is now responding to "hockey".
