bash returns wrong variable value/call more proccesses?

Bug description:
Simple function gives different results when interpretator set in first
string of script
CHECKPROC()

i=$(ps aux | grep -c $0)
ps aux | grep -c $0

CHECKPROC
Expected
In any conditions it will return same values, then will increments when other
copies of script will be found in proccesses list.
Happened.
We set interpretator with #!/bin/bash or #!/bin/sh in first string of script
and runs multiple copies of script from one terminal with & after scriptname.
It's returns "1" and "variable is 1" always.
Without interpretator setup, when string #!/bin/bash or #!/bin/sh deleted.
Run multiple copies scriptname.sh&
On every iteration it returns right first value and "variable is $value+1"
$scriptname.sh&
2
variable is 3
$scriptname.sh&
3
variable is 4
...and so on.
Without counting in first case it returns only string with grep, in
second case -- one more string with different PID and script name when
called from i=$(...) or i=`...`

Brian Murray (brian-murray)
It's tested other man on ubuntu 20.04 x64 and apple mac pro with m1 pro CPU.
GNU bash, version 5.1.16(1)-release (aarch64-apple-darwin21.1.0)
GNU bash, version 4.4.20(1)-release (x86_64-pc-linux-gnu)
I will test it from lubuntu 20.04 x64 livecd and will add new results.
...
Tested on Lubuntu 20.04, results are the same.

Trusty is no longer a supported release of Ubuntu. Have you tested this
with a supported release of Ubuntu? If so what version of bash were you
using?

[Touch-packages] [Bug 1958060] Re: bash returns wrong variable value/call more proccesses?
up.
String without shebang returns 0 for pgrep -c $0 or 1 for ps aux | grep -c $0.
Solved with help of user Valrust from forum.ubuntu.ru, it's standart behavior
of the system.
In that case new copy of script runs as "bash" without agruments and try to
find /address/name.sh in ps aux returns nothing, but pgrep -c bash returns more
and more values depends from run copies.
