Same thing can happen to bitcoin,
the biggest difference is that someone would, uh, notice.
Who said they don't, but btc requires 3 confirmations,
so the below list of less than 3 confirmations is also ignored as it is below the required confirmations.

Orphaned Blocks
Detached or Orphaned blocks are valid blocks which are not part of the main chain.
They can occur naturally when two miners produce blocks at similar times
or they can be caused by an attacker (with enough hashing power) attempting to reverse transactions.

https://en.bitcoin.it/wiki/Chain_Reorganization
The term "blockchain reorganization" is used to refer to the situation where a client discovers a new difficultywise-longest well-formed blockchain which excludes one or more blocks that the client previously thought were part of the difficultywise-longest well-formed blockchain. These excluded blocks become orphans.
With BTC wait 3 confirms to be assumed safe.
With BCH wait 6 confirms to be assumed safe.
Any reorg higher than those #s,
then double spends could occur, and then you have the panic, anything below those #s, and no one really cares.
