In practice, you will hear many ops sending prosigns wrongly. There are quite a few seasoned ops who refuse to answer messages sent in such an unclear way.
Very amusing! :)
It's a bit of a vexed issue, sometimes leading to much acrimony ( bad habit morse ) - as does some people's ( unhelpful, pedantic ( but not teaching ), condescending ) response to it.
People don't tend to listen to their own sending very much.
Periodically one of the old boys has a go at raising the issue and getting us all back into line a bit . .

Accuracy before speed.
Despite what some people seem to think , this is not a speed trial ( except between friends / rivals of course )
