Would I be right to assume that this advice does not apply when you're going
to read the file immediately after writing it?

In general, yes. However, it really depends on the size of the file. If the file is way bigger than physical memory, the disk cache will probably do completely the wrong thing (LRU), so non-cached writes are better. If the file is way smaller than physical memory, caching it is a fine idea.
