Is it considered as anadiplosis (顶真) when the same character repeats but means differently?
頂真 is a rhetoric method to make sentences reading more smoothly or meaning more tightly.
The connected words should be the same meaning. Check the following examples:

將軍百戰死，壯士十年歸。歸來見天子，天子坐明堂: 歸-&gt;come back, 天子-&gt;emperor
江南可採蓮，蓮葉何田田: 蓮-&gt;lotus
我出了村就過了河，過了河就進了城: 過了河-&gt;across the river

But for your example like:

度 is part of India (印度) on the left and means &quot;passing&quot; on the right.
光 is part of &quot;time&quot; (時光) on the left and part of the adverb &quot;just&quot; (光是) on the right.

These above should not be counted as proper anadiplosis rhetoric method, maybe only 历 (past meaning in general).
