Question re:new phal spike and old spike

[modernmissus]

Hello all, I have question, I have had a phal that has been amazingly awesome!

It grew a spike that has been blooming for literally 2 years with minimal breaks. It kept growing new buds on the end of the original spike, and then when that finally stopped and I cut the spike to just above a node, it grew another stem off the original spike. This then continued to grow buds on the end of the spike as well! I've never had an orchid do this, I'm not sure why it kept growing new buds?

So when it recently seemed to have stopped again, I cut it back again to just above a node. Now I've noticed it is growing a new spike as well as another new growth off the original spike! This orchid hasn't had a rest in 2 years! Should I just enjoy this, or should I cut the old spike to give more energy to the new one?

Sorry for the long post! Any information would be greatly appreciated. Thank you!
