No: in your case, the text property covers characters between positions
1 to 4, and point is at position 4 (right in front of the char at
position 4 and right after the char at position 3), i.e. right on the
boundary of the text-property.  When on the boundary, the behavior will
depend on whether the property is sticky or not, so you can control it
by twiddling the "front-advance, read-advance" settings of your overlays
or the rear-non-stick and front-sticky text-properties.
