[yocto] for MPC8315E-RDB ref board, is CONFIG_SYS_MONITOR_LEN set too low?

it's possible i'm just hopelessly misreading something, but i just
built (using pure defaults) an image for my MPC8315E-RDB dev kit, and
while the current board config header file
include/configs/MPC8315ERDB.h contains:
/*
* The reserved memory
*/
#define CONFIG_SYS_MONITOR_LEN (384 * 1024) /* Reserve 384 kB for Mon */
the actual u-boot binary constructed for this target was:
-rwxr-xr-x. 2 rpjday rpjday 423964 Jul 5 06:46 \
u-boot-mpc8315e-rdb-v2016.03+gitAUTOINC+df61a74e68-r0.bin
given that that same file defines:
#if !defined(CONFIG_SYS_RAMBOOT)
#define CONFIG_ENV_IS_IN_FLASH 1
#define CONFIG_ENV_ADDR \
(CONFIG_SYS_MONITOR_BASE + CONFIG_SYS_MONITOR_LEN)
isn't that going to result in persistent u-boot environment being
saved over top of the tail end of u-boot in NOR flash?
or am i just confused?
