I think he didnt say the name of it because it a secret fobiden technique.

Many people have also ssid and believe 4tail mode isnt "That Jutsu" so im going by the most reasonable explanation.
When speaking on behalf of the community, you shouldn't use choice words such as "I think" and "i believe"

Likewise, many people have also said and believe 4tail mode IS that jutsu.
Jiraiya isn't going to teach Naruto a forbidden jutsu and then say "don't use that jutsu"

What's the ripoff? Coming up with a traditional method to discovering the biological capacities of a fictional character in a supernatural world? Oh yeah, HxH must've taken the rights to THAT one.
For the record, this doesn't differ too much from jiraiya's "chakra rotation" test with naruto's hairline to see how Naruto's chakra naturally rotates through his body.
