It really is not the same. Also, the up/down being squished to half their normal height makes things more difficult. In other words, there is just a lot less room for error, now..

The up/down arrow keys are sized as they were before. It's the left/right arrow keys that have grown to be twice their normal height.

On the magic keyboard, the whole bottom row of keys is shorter than they used to be. Not by a lot, but they're shorter. They're now the same height as the keys above.
