Give other (more important reason) for refactoring code in Super Rentals tutorial

In the Super Rental tutorial, [Part 1, Interactive Components](https://guides.emberjs.com/release/tutorial/part-1/interactive-components/#toc_testing-user-interactions) it is suggested that this code
```hbs
{{#if this.isLarge}}


View Smaller

{{else}}


View Larger

{{/if}}
```
be refactored into this code
```hbs

View {{if this.isLarge "Small" "Large"}}

```
the main reason given is code readability but in my opinion the use of the same image element, without removing one and creating another, is much more important, as when you use the first example the image loads each time isLarge is changed, causing a much worst user experience. This is a very important reason for refactoring that, in my opinion, should be outlined in the guide.
