This is correct! Thanks Frank.
I asked Academy Games a similair question. This was their response:
You can hold any number of tokens (conductor, fundraising, or support) at one time, but you can only spend up to two tokens during your Action phase. If you receive another token through the purchase of an abolitionist card, you can spend the token you receive only if you have not already spent two tokens in that Action Phase.
If you have already spent two tokens, then you can hold onto the token to use in a future Action Phase. If you were to do this you would still be allowed to purchase up to two tokens in the next Planning phase.
