I don't know where you get your info from, but I'd like some prooflink. Both ingame stats and Warframe builder do not increase elemental damage after adding physical. In theory what you say makes sense, and then the devs are really sloppy on this one. However, just like Vitality\Redirection - physical mods may work just like elem mods. They increase BASE damage only. And base damage is scaled only by total damage, like Serration. So naturally physical mods - are just elemental mods, with the exception that an elemental mod adds damage based on total physical, while single physical only increases it's own.

What the original poster meant is that, say, for a weapon that has 100 damage, 80 of which is Impact - adding 90% elem would add all 90 elem damage. While adding 90% impact would only be 72.

What you meant, theoretically, is that if a damage has already 1 elem mod which is clearly better, a choice whether to add 2nd elem or not would end up:

2nd standalone elem mod - 90 more damage

impact mod - 72 damage, 90% of which, ~65 - would be added to first elemental mod, since the weapon damage is not 100, but 172, so 90% of it is not 90, but 155.

Until I can see proof of it(and I have no time or will to test it on enemies(it's high time they should introduce dojo target dummies)), I can only agree that adding 90% physical damage to major physical weapon would be better(and cheaper) than shocking touch or north wind(60% only).
