The "bootz" command is implemented in the "bootm", so the dependency should be reflected in Kconfig.

depends on CMD_BOOTM help Boot the Linux zImageif bootz already depends on bootm, why then do you need to select both?
To avoid unmet dependency.
I recommend you to read Linux's Documentation/kbuild/kconfig-language.txt, especially the following part:
- reverse dependencies: "select" <symbol> ["if" <expr>] While normal dependencies reduce the upper limit of a symbol (see below), reverse dependencies can be used to force a lower limit of another symbol. The value of the current menu symbol is used as the minimal value <symbol> can be set to. If <symbol> is selected multiple times, the limit is set to the largest selection. Reverse dependencies can only be used with boolean or tristate symbols. Note: select should be used with care. select will force a symbol to a value without visiting the dependencies. By abusing select you are able to select a symbol FOO even if FOO depends on BAR that is not set. In general use select only for non-visible symbols (no prompts anywhere) and for symbols with no dependencies. That will limit the usefulness but on the other hand avoid the illegal configurations all over.
