"Anybody who doesn't know what is meant by alignment hasn't been taught correctly."
This would apparently include yourself, as you've still failed to produce a definition, for it.
"both the body and the feet are on the same alignment in the Whisk. Is that correct or not."
No, it is not correct.
Promenade, as anyone with any actual experience of dancing knows, requires that both partners have an angle between their feet and their topline. Classically this would be 45 degrees, but on some such as Jonathan, it can be nearly 90 degrees - feet pointing down LOD, body facing wall.
The whisk may tend to be a bit sloppy compared to other promenade entries, but it still requires a notable angle between feet and shoulders in both partners.
