I understand what you're doing and why you're doing it but that is not correct usage of this syntax. It always goes by height resolution, you're using width resolution. For example both 1280 x 720 (16:9 aspect ratio) and 960 x 720 (4:3 aspect ratio) are considered 720p. 1280 x 720 is commonly associated with 720p simply because most content out there is 16:9 aspect ratio, but of course dolphins internal resolutions are not.
Approximate values:
1x is 480p
1.5x is 720p
2x is 960p
2.5x is 1200p
3x is 1440p
4x is 1920p
Exact values:
1x is 528p
1.5x is 792p
2x is 1056p
2.5x is 1320p
3x is 1584p
4x is 2112p

Most GC games and some Wii games don't even support widescreen aspect ratios. And in that case the above values are what you need to meet/exceed those resolutions. Your values only correspond to games running in widescreen mode. Since both dolphin and the real hardware handles widescreen in an anamorphic manner I feel that my values are more "proper" in this sense as well.

And of course this is just going by internal resolution (the resolution of the image that dolphin renders). There is also your fullscreen/windowed resolution to consider (the resolution that dolphin outputs). In order for you to actually be able to see 720p or 1080p your internal resolution, fullscreen resolution (if you're running dolphin in fullscreen mode), windowed resolution (if you're running dolphin in windowed mode), and screen resolution (the resolution of your display) all have to be at or above a height resolution of 720 for 720p and 1080 for 1080p.
Dolphin also has auto window size which automatically matches the internet resolution to your fullscreen/windowed resolution. And auto multiple of 640 x 528 which automatically selects between 1x, 2x, 3x, and 4x based on your fullscreen/windowed height resolution.
Dolphin always outputs progressive scan content since computer monitors and HDTVs are always progressive scan displays.
On an actual GC you have to choose between composite, s-video (NTSC regions only), or rgb scart (PAL regions only) video output. And in all three cases you're limited to 480i. Which means 640 x 480 for a game that's running in fullscreen mode and 854 x 480 for a game that's running in widescreen mode. And interlaced scanning.
On a Wii you have those three video output options plus component. With component output you can configure the Wii and your games to run at either 480i or 480p (the same resolution but with progressive scanning).
LCD, DLP, and PDP (plasma display panel) HDTVs are progressive by nature. So they have to convert any interlaced content they receive into progressive content before they can display it using a deinterlacer. Since the type of deinterlacer used varies from one TV to another you'll see different results. And as such the difference in perceived quality between 480i and 480p depends completely on what TV model you're using.
Since it takes awhile to appropriately explain the differences between interlaced scanning and progressive scanning in a way that anyone can understand I would recommend that you just read that wikipedia article that pauldacheez linked instead.
Edit: Or watch that video.
