I get that. However could the same not be achieved without actually consuming the whitespace, eg with lookahead/lookbehind?

Unfortunately lookbehinds can not be variable length. And since we want to allow arbitrary amount of spaces between "tokens" this is the solution we need to adopt. I can not see a good reason for why say [a-z]* should not be able to be used in a lookbehind but that is the case.
Sorry for calling you Hans by the way, for some reason I assumed you were Hans-Jörg Bibiko.
