Rule not working in rewrite rules despite valid regex - regex

Question

Our webconfig file uses Url Rewrite, essentially pushing any http traffic to https
This works fine other than developing locally. For a while we have to simply remember to comment out the code from the web.config and uncomment it again for commit. Naturally this isn't a good way to work.
The code is simple
<rewrite>
<rules>
<rule name="Redirect-AllWWW-ToSecureNonWWW">
<match url="^((?!local).)*$" />
<conditions>
<add input="{HTTP_HOST}" pattern="^(?:www\.)(.+)$" />
</conditions>
<action type="Redirect" url="https://{C:1}/{R:0}"/>
</rule>
<rule name="Redirect-AllNonSecure-ToSecureNonWWW-ExcludingLocalhost">
<match url="^((?!local).)*$" />
<conditions>
<add input="{HTTP_HOST}" pattern="^localhost$" negate="true" />
<add input="{HTTPS}" pattern="^off$" />
<add input="{HTTP_HOST}" pattern="^(?:www\.)?(.+)" />
</conditions>
<action type="Redirect" url="https://{C:1}/{R:0}" />
</rule>
</rules>
</rewrite>
And as per the regex101 , it works!

However, when on localhost, I am still directed to HTTPS
Why does it work in regex101 and not in my web.config file

This seems to be related to Redirect rule not working
quote from URL Rewrite Module Configuration Reference
A rewrite rule pattern is used to specify a pattern to which the current URL path is compared.
...
A pattern is specified within a <match> element of a rewrite rule.
According to this piece of official information, you must be sure that <match url compares only with URL paths which never contain host names, not the entire URL.
For Url Rewrite Module, URL path of this question is questions/44944175/rule-not-working-in-rewrite-rules-despite-valid-regex for example. No stackoverflow.com no https:// no query strings but only the path without leading slash.
To ignore requests for host names containing local you need some conditions looking for a local match with HTTP_HOST header.
<rewrite>
<rules>
<rule name="Redirect-AllWWW-ToSecureNonWWW" stopProcessing="true">
<match url=".*" />
<conditions>
<!-- continue if http host name does not contain "local" -->
<add input="{HTTP_HOST}" pattern="local" negate="true" />
<add input="{HTTP_HOST}" pattern="^(?:www\.)(.+)$" />
</conditions>
<action type="Redirect" url="https://{C:1}/{R:0}" />
</rule>
<rule name="Redirect-AllNonSecure-ToSecureNonWWW-ExcludingLocalhost" stopProcessing="true">
<match url=".*" />
<conditions>
<!-- continue if http host name does not contain "local" -->
<add input="{HTTP_HOST}" pattern="local" negate="true" />
<add input="{HTTPS}" pattern="^off$" />
<add input="{HTTP_HOST}" pattern="^(?:www\.)?(.+)" />
</conditions>
<action type="Redirect" url="https://{C:1}/{R:0}" />
</rule>
</rules>
</rewrite>
