This is my point. The <local> should be visible for both or for none.

If <m/> and <antcall> do not make local p visible,
then one simply gets:
x:
[echo] my global p
<macrodef name="m">
<sequential>
<echo>${p}</echo>
<antcontrib:if>
<equals arg1="${p}" arg2="my local p"/>
<then>
<antcall target="tm"/>
</then>
</antcontrib:if>
</sequential>
</macrodef>
<target name="x">
<local name="p" value="my local p"/>
<m/>
</target>
<target name="tm">
<echo>${p}</echo>
</target>
<property name="p" value="my global p"/>
