Mention the first immediate action in an '-ing' clause in front of the main clause

Page 585 of the Collins English Usage reads

To indicate that someone did one thing immediately after
another, you can mention the first thing they did in an ‘-ing’ clause
in front of the main clause.

Leaping out of bed, he dressed so quickly that he put his boots on the
wrong feet.

However, I find the semantics of the example jarring, because leap is an action that takes just a moment, unlike for example He used to shave, comb and get dressed while cooking breakfast.
