Its not mandatory, but yes, might be the cause for errors.
However, i tend more to say its the multiple commands you want to execute.
So, i'd suggest make 2 scripts.
1 script to check whether script is already running, and if so closes it,
or otherwise calls the other one, domexpcheck.sh.
And execute just the 'new' script in crontab, which then will execute the domexpecheck.sh

rc3(8) System Manager's Manual rc3(8)
NAME
rc3 - Run command script executed when entering a multiuser run level
SYNOPSIS
rc3
DESCRIPTION
The rc3 script contains run commands that enable initialization of the system to a multiuser state; run level 3. In addition to commands
listed within the script itself, rc3 contains instructions to run certain commands found in the /sbin/rc3.d directory. The script defines
the conditions under which the commands execute; some commands run if the system is booting, other commands execute if the system is chang-
ing run levels.
By convention, files in the rc3.d directory begin with either the letter "S" or the letter "K" and are followed by a two-digit number and a
filename; for example: S00inet S55inetd S70mount S65lpd
In general, the system starts commands that begin with the letter "S" and stops commands that begin with the letter "K." Commands that
begin with the letter "K" run only when the system is changing run levels from a higher to a lower level. Commands that begin with the
letter "S" run in all cases. The numbering of commands in the /sbin/rc3.d directory is important since the numbers are sorted and the com-
mands are run in ascending order. Files in the /sbin/rc3.d directory are normally links to files in the /etc/init.d directory.
An entry in the inittab file causes the system to execute the rc3 run commands, for example: s3:3:wait:/sbin/rc3 < /dev/console > /dev/con-
sole 2>&1
The following operations are typical of those that result from executing the rc3 script and the commands located in the /sbin/rc3.d direc-
tory. The operation depends on which state the system is entering or exiting. Setting the time zone Checking the current run level Start-
ing network services and daemons Starting (or stopping) system services and daemons Mounting file systems
Setting the TIMEZONE variable is one of the first operations completed by the rc3 script. This action provides the default time zone for
subsequent commands.
