This is false,
a segwit transaction to the miner you describe is an "everyone can spend"
transaction, and as such a miner that does not validate the segregated area
in a post-segwit world will be able to create blocks that will not validate
for segwit miners by including a transaction that spends a SW tx.
This would then lead to a chain-fork as the SW miners reject it and the non-
SW miners continue to mine on it.
