I don't think I misunderstood and you didn't seem to read the article. It quotes Eddie and references the same song and show. Feel free to post an article where Eddie says he couldn't play the guitar solo that Jimmy Page played and so he had to use tapping to simulate it. He took the technique and realized it could be applied a certain way.I think you misunderstand- Eddie and Alex went to a Zeppelin concert at the LA Forum around 1972 and they saw Page do a pull-off slide move down the neck. Eddie couldn't do that, so he simulated it with tapping. The rest is history. He's stated this in many interviews.
Props to Pacfanweb for posting that video where he explains it. Here are more articles.
"But it was watching Led Zeppelin at the Los Angeles Forum in the early 1970s that changed his guitar playing forever. A light bulb went off as Jimmy Page played the solo from Heartbreaker, using both hands to tap out notes on the neck of the guitar.
For Page, it was an opportunity to showboat - but Eddie took the technique and refined it, enabling him to play a seemingly impossible flurry of notes and pinched harmonics.
"It's like having a sixth finger on your left hand," he explained in 1978 "Instead of picking, you're hitting a note on the fretboard."
The approach was so revolutionary that Alex encouraged his brother to play with his back to the audience so other bands wouldn't steal it before Van Halen had a record deal."
This is from the BBC. If you notice the "he explained in 1978", it is a link and direct quote from Eddie himself.
5 Eddie Van Halen Songs That Prove He Was About More Than Just Speed
Eddie Van Halen revolutionized the guitar. “Revolutionized” may be a strong word, but it’s accurate. The iconic guitarist, who died Oct. 6 at the age of 65 from throat cancer, was one of only a handful of guitarists to pick up the instrument and make the entire guitar community place...

"Thankfully for Eddie Van Halen, most people had no idea how he was able to play so fast. During an event hosted by the Smithsonian Museum of American History, he claimed to have witnessed Jimmy Page at the Los Angeles Forum playing his guitar solo on “Heartbreaker” with only his left hand, as his right was up in the air. Van Halen realized at that point that one could simply do that, but with both hands, allowing for an expanded range of notes and much faster playing, a technique later to be called “tapping.” “I never heard anyone do [with that technique] what I did, which was actual pieces of music,” Van Halen had said.
