Unique Overworld Boss (a la DoomGaze)/Creating New Area Question

[danyetman]

Code:

CA/5338: A0    Set timer 0 to $0040 [0m: 01s: 04j], jump to subroutine $CA533F if it expires. Flags:  
               (Countdown pauses in menu and battle)
               (Countdown not shown while walking)
               (Unknown flag 0x20 disabled on event bank byte)
               (Countdown does not override the game clock display)

Are you sure about that? My disassembly states that CA/5338: A0 is "Move character right/up 1x1 tiles".
