A different Mode name is required when explaining the difference in sound between a C scale starting on C and the C scale starting on D. They don't sound the same, but they are the same scale (series of notes).
Ionian is the 'collective sound' of all the white notes on a piano when you start and end on C.
Dorian is the 'collective sound' of all the white notes on a piano when you start and end on D.
The reality of the situation is that you're going to rarely start and end your phrases on a single note, so the talk of modes in relation to 'modal jazz' is incorrect use of the term.
When 'modal jazz' was coined it was done so by folks that really didn't understand the usage of the term in pre-existing 'classical' music. Once scholars/musicians thought about it some more, they realized that's not what 'modal jazz' was about at all.
Having said that, simply stated, a musical line is either 'being there' or 'going there'. With 'modal jazz' it's all about playing lines that are 'being there'. Sometimes it uses sounds that had traditionally been used as 'going there' sounds, but now making them sound like 'being there'...
Like making a mixolydian or lydian dominant sound settled -- 'being there.'
