Well in the end, ETH didn't go over bitcoin, they always stay in 1-2 position exactly as it is. Last year when the market was high, bitcoin price didn't go up as much as ethereum neither, the difference went under 2x for a while, which means that ETH got very close but yet no matter what happens it didn't drop any lower.
This is why I keep saying that it is a lot better if we could like ETH for what it is, but do not consider it as the way bitcoin will go down under first position eventually. I also believe that if one day bitcoin is not the first coin in the rankings, that could be a very risky and dangerous thing as well, I would be a little scared.
There are reasons on why eth are still on the second place and won't overcome btc easily. It can be because of its supply because we know that eth has an unknown supply before but now that it was upgraded to eth 2.0 I think its supply is known now but it might still be higher than on what btc have. Eth is also centralized and many people doesn't like that fact.
We only think that the increase on eth is higher than in btc because it is a much smaller coin but at the end of the day, btc can still win this competition. The foundation that btc already built is already strong and it will hard to destroy anymore but it will only be added for more.
