That interview pretty much explains the important take away of the song. I think people are concentrating too much on 1:1 the lyrics however (this is not always fruitless), and not enough on how contextually, the overall meaning of the song is what is being applied for the game. Which admittedly, is much more underlying in the more secretive information as opposed to blatant, if viewed on by first timers.
The foundational meaning of "Cloud's inner feelings; point of view" to the general approach of the lyrics "a man losing something important"—if taking a look at how it was used for the game, it comes out of something of the sort: "Clouds [a person's] feelings about losing something important". The most blatant application of the song goes to the ending, where it qualifies for retaining the meaning of all applicable things that represents Cloud's story in varying degrees: his inner self/memories, Aerith, and Zack—at least two of these things directly connect to the Nibelheim incident as well. However, in this ending we also see how Aerith is the one that this meaning represents, this being apparent by her last line for the game, which is much more direct in JPN, but can still be found in the ENG version as well.
If the theme continues to be in the other games, I wouldn't be surprised if we have some interludes of it played in other moments that represent someone losing something important, especially if it gravitates around what Cloud lost. I do still believe it is a mistake though to just go with just "song is about X person". It's just too generally applied, but my above banter, outside of what was explicitly stated in the interview, can just be taken as interpretation anyway I guess. That being because I don't really know the reason why it's the Sector 5 theme. If I had to take a stab, it would be what I stated prior—they're just going to apply it in the series where that meaning can be found. Between Cloud and Aerith's losses being expressed in the game in different ways, I'm sure it's somewhere in the middle for being represented there.
