No I'm not
It's like if someone says "do you have a good job" and you say "I did". "Did" being the past tense of "do" - thus emphasing the lack of having a good job in the present tense. Since "could" is the past tense of "can", as well as the conditional present (or something), then this could be what Americans mean.
