Does hotstring naming matter, or just the keysequence?

I 'm not able to get the party speak to work. I have a bit of variablity in the hotstring names:

I've named one key lbta, and another lbtoonb, etc. could this be my problem?
in general ony the keysequence. so its not important if you name the hotstring for lightning bolt 'lbta' or 'lbtoonb', the only thing thats important is, that you use the same name for the hotstring identifiying lb on a specific Toon, like 'lightning.bolt.on.ToonAs.target' in every keymap.

So using:

'ctrl + shift + i ---> lightning.bolt.on.ToonAs.target'' on the Keymap of ToonB
and
'ctrl + shift + i ---> lbA'

is a no go!
