Yes, but Vettel doesn't take a late apex there. It's still a conventional apex.
In the absence of good diagrams I have decided to create my own diagram. It's a rather extreme example of a late apex, to illustrate the point more easily
Presenting...
The Late Apex
Basically, what JT was saying, by getting on power before halfway into the corner, is that you start getting on the power at arrow 7. Arguably that is before the midway point of the corner (geometrically). Ultimately your apex speed (between arrows 6 and 7) is sacrificed, for a better exit.
JT - correct me if I'm wrong, but this is exactly what you're saying - correct?
In any case - I'm done with trying to explain it to you. It's like trying to talk to a theoretical engineer.
