Cortex R5 cache policy set to write through , behavior of read

I see in the cortex R5 technical reference manual , it is mentioned as below for write through cache policy

Write-through. With this policy writes are performed to both the cache and main memory.
This means that the cache and main memory are kept coherent. As there are more writes
to main memory, a write-through policy is slower than a write-back policy if the write
buffer fills. Therefore write-through is less commonly used, although it can be useful for
debug. Regions marked as write-through are treated as non-cacheable.

It says " Regions marked as write-through are treated as non-cacheable." Does this mean, if a region is marked as write through, then reads in that region are also not cached?
