Yes, and no. In this case, there will be another split because community and miners(not as much) are divided as to which Bitcoin to support. Many people also claim that 2MB is useless now that we have Bitcoin Cash.
Future forks don't necessarily mean new coins. It depends on the miner & community support a coin has. Should Bitcoin need another hard fork, without any politics (meaning 100% support) there won't be a split.
I've written a post on post-SegWit Bitcoin and the consequences of a split here if you'd like to check it out.
