This won't work, since the RESTORE_REGISTER will always be triggered, 
even if there was no LOAD_REGISTER at all - so it might break other 
register values.

Try this one instead

lib.contactbox = COA
lib.contactbox {
     10 = LOAD_REGISTER
     10.myPlugin.cObject < plugin.tx_myext_pi1

     20 = TEXT
     20.data = register:myPlugin

     30 < styles.content.get
     30.select.where = colPos = 3

     40 = TEXT
     40.value = </div>
     40..if.isTrue.data = register:myPlugin

     50 = RESTORE_REGISTER
}

or without registers but "current" instead
(not tested but should be working according to TSref)

lib.contactbox = COA
lib.contactbox {
     10 = TEXT
     10.setCurrent.cObject < plugin.tx_myext_pi1
     10.current = 1

     20 < styles.content.get
     20.select.where = colPos = 3

     30 = TEXT
     30.value = </div>
     30.if.isTrue.current = 1
}

Done :-)
